	DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION
	Perma-Fix Environmental Services, Inc. (the Company, which may be referred to as we, us, or our), an environmental and technology know-how company, is a Delaware corporation, engaged through its subsidiaries, in two reportable segments:
	TREATMENT SEGMENT, which includes:
		-	nuclear, low-level radioactive, mixed waste (containing both hazardous and low-level radioactive constituents), hazardous and non-hazardous waste treatment, processing and disposal services primarily through four uniquely licensed and permitted treatment and storage facilities; and
		-	research and development activities to identify, develop and implement innovative waste processing techniques for problematic waste streams.
	SERVICES SEGMENT, which includes:
		-	On-site waste management services to commercial and government customers;
		-	Technical services, which include:
		o	professional radiological measurement and site survey of large government and commercial installations using advanced methods, technology and engineering;
		o	integrated Occupational Safety and Health services including industrial hygiene (“IH”) assessments; hazardous materials surveys, e.g., exposure monitoring; lead and asbestos management/abatement oversight; indoor air quality evaluations; health risk and exposure assessments; health & safety plan/program development, compliance auditing and training services; and Occupational Safety and Health Administration (“OSHA”) citation assistance;
		o	global technical services providing consulting, engineering, project management, waste management, environmental, and decontamination and decommissioning field, technical, and management personnel and services to commercial and government customers;
		-	Nuclear services, which include:
		o	technology-based services including engineering, decontamination and decommissioning (“D&D”), specialty services and construction, logistics, transportation, processing and disposal;
		o	remediation of nuclear licensed and federal facilities and the remediation cleanup of nuclear legacy sites. Such services capability includes: project investigation; radiological engineering; partial and total plant D&D; facility decontamination, dismantling, demolition, and planning; site restoration; site construction; logistics; transportation; and emergency response; and
		-	A company owned equipment calibration and maintenance laboratory that services, maintains, calibrates, and sources (i.e., rental) of health physics, IH and customized nuclear, environmental, and occupational safety and health (“NEOSH”) instrumentation.
	The Company’s consolidated financial statements include our accounts and the accounts of our wholly-owned subsidiaries as follows. The Company’s financial statements also include the accounts of SEC Radcon Alliance, LLC ("SECRA"), which we own 75% and Perma-Fix Medical S.A., which we own 64%.
	Continuing Operations: Diversified Scientific Services, Inc. (“DSSI”), East Tennessee Materials & Energy Corporation (“M&EC”), Perma-Fix of Florida, Inc. (“PFF”), Perma-Fix of Northwest Richland, Inc. (“PFNWR”), Schreiber, Yonley & Associates (“SYA” which was divested on July 29, 2014), Safety & Ecology Corporation (“SEC”), Perma-Fix Environmental Services UK Limited, Perma-Fix of Canada, Inc., SECRA (which we own 75%), and Perma-Fix Medical S.A. (a 64% owned Polish subsidiary acquired on April 4, 2014, whose primary purpose is the research and development and marketing of medical isotope technology used in medical diagnostic testing – See Note 4 – “Perma-Fix Medical S.A.” below for further details of this subsidiary).
	Discontinued Operations (See “Note 8”): Consist of all our subsidiaries included in our Industrial Segment which were divested in 2011 and prior, two previously closed locations, and our Perma-Fix of South Georgia, Inc. (“PFSG”) facility which suffered a fire on August 14, 2013 which has left it non-operational.
	Reduction In Authorized Shares and Reverse Stock Split
	On September 18, 2014 at the Company’s 2014 Annual Meeting of Stockholders, the Company’s stockholders approved an amendment to the Company’s Restated Certificate of Incorporation to reduce the number of shares of Common Stock the Company is authorized to issue from 75,000,000 to 30,000,000. This amendment became effective on September 19, 2014.
	Effective as of 12:01 a.m. on October 15, 2013, the Company effected a reverse stock split at a ratio of 1-for-5 of the Company’s then outstanding Common Stock and shares of Common Stock issuable upon exercise of the then outstanding stock options and warrants. All references in the financial statements and notes thereto to the number of shares outstanding, per share amounts, and outstanding stock options and warrant data of the Company’s Common Stock reflects the effect of the reverse stock split for all periods presented. In addition, the shares available for issuance under the Company’s various stock option plans reflect the effect of the revese stock split. The reverse stock did not affect the number of authorized shares of Common Stock which had remained at 75,000,000 through September 19, 2014.
	Financial Position and Liquidity
	The Company achieved substantial improvements in financial position and liquidity in the twelve months ended December 31, 2014 as compared to the corresponding period of 2013. As of December 31, 2014, we had cash on hand of approximately $3,680,000, no revolver balance, and a working capital of approximately $757,000 as compared to a working capital deficit of $2,498,000 as of December 31, 2013. Our working capital for 2014 was positively impacted by the insurance settlement proceeds that the Company received from its insurance carriers for our Perma-Fix of South Georgia, Inc. subsidiary (“PFSG”), proceeds received from the sale of our SYA subsidiary, and the receipt of certain proceeds from the Company’s Polish subsidiary, Perma-Fix Medical S.A., that it received due to the sale of certain equity (see Note 8 - “Divestitures and Discontinued Operations” and Note 4 - “Perma-Fix Medical S.A.” for further information of these proceeds).
	The Company’s cash flow requirements during 2014 were financed by cash on hand, operations, credit facility, and the proceeds received as discussed above. The Company is continually reviewing operating costs and is committed to further reducing operating costs to bring them in line with revenue levels, when needed.
	The Company’s cash flow requirements for 2015 will consist primarily of general working capital needs, scheduled principal payments on our debt obligations and capital leases, remediation projects and planned capital expenditures which we plan to fund from operations and our credit facility.

Note_2_Summary_of_Significant_

Note 2 - Summary of Significant Accounting Policies	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	NOTE 2
	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Principles of Consolidation
	Our consolidated financial statements include our accounts and those of our wholly-owned subsidiaries after elimination of all significant intercompany accounts and transactions. The consolidated financial statements also include the accounts of SECRA, which we own 75%, and Perma-Fix Medical S.A., which we own 64%.
	Reclassifications
	Certain prior year amounts have been reclassified to conform with the current year presentation.
	Use of Estimates
	When the Company prepares financial statements in conformity with accounting standards generally accepted in the United States of America (“US GAAP”), the Company makes estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, as well as, the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. See Notes 8, 11, 12 and 13 for estimates of discontinued operations and environmental liabilities, closure costs, income taxes and contingencies for details on significant estimates.
	Restricted Cash
	Restricted cash reflects $35,000 held in escrow for our worker’s compensation policy and $50,000 held in escrow in connection with the divestiture of SYA on July 29, 2014 to be used to cover any potential claims made by the purchaser for indemnification for certain limited types of losses incurred by the purchaser within one year of the divestiture of SYA (see Note 8 – “Divestitures and Discontinued Operations” for further detail of this $50,000).
	Accounts Receivable
	Accounts receivable are customer obligations due under normal trade terms requiring payment within 30 or 60 days from the invoice date based on the customer type (government, broker, or commercial). The carrying amount of accounts receivable is reduced by an allowance for doubtful accounts, which is a valuation allowance that reflects management's best estimate of the amounts that will not be collected. We regularly review all accounts receivable balances that exceed 60 days from the invoice date and based on an assessment of current credit worthiness, estimate the portion, if any, of the balance that will not be collected. This analysis excludes government related receivables due to our past successful experience in their collectability. Specific accounts that are deemed to be uncollectible are reserved at 100% of their outstanding balance. The remaining balances aged over 60 days have a percentage applied by aging category, based on historical experience that allows us to calculate the total allowance required. Once we have exhausted all options in the collection of a delinquent accounts receivable balance, which includes collection letters, demands for payment, collection agencies and attorneys, the account is deemed uncollectible and subsequently written off. The write off process involves approvals from senior management, based on, required approval thresholds.
	Retainage receivables represent amounts that are billed or billable to our customers, but are retained by the customer until completion of the project or as otherwise specified in the contract. Our retainage receivable balances are all current. Retainage receivables of approximately $11,000 and $135,000 as of December 31, 2014 and 2013, respectively, are included in the accounts receivable balance on the Company’s Consolidated Balance Sheets in the respective periods.
	Unbilled Receivables
	Unbilled receivables are generated by differences between invoicing timing and our performance based methodology used for revenue recognition purposes. As major processing and contract completion phases are completed and the costs incurred, we recognize the corresponding percentage of revenue. Within our Treatment Segment, we experience delays in processing invoices due to the complexity of the documentation that is required for invoicing, as well as the difference between completion of revenue recognition milestones and agreed upon invoicing terms, which results in unbilled receivables. The timing differences occur for several reasons: partially from delays in the final processing of all wastes associated with certain work orders and partially from delays for analytical testing that is required after we have processed waste but prior to our release of waste for disposal. The tasks relating to these delays usually take several months to complete. As we now have historical data to review the timing of these delays, we realize that certain issues, including, but not limited to, delays at our third party disposal site, can extend collection of some of these receivables greater than twelve months. However, our historical experience suggests that a significant part of unbilled receivables are ultimately collectible with minimal concession on our part. We, therefore, segregate the unbilled receivables between current and long term.
	Unbilled receivables within our Services Segment can result from: (1) revenue recognized by our Earned Value Management program (a program which integrates project scope, schedule, and cost to provide an objective measure of project progress) but invoice milestones have not yet been met and/or (2) contract claims and pending change orders, including Requests for Equitable Adjustments (“REAs”) when work has been performed and collection of revenue is reasonably assured.
	Inventories
	Inventories consist of treatment chemicals, saleable used oils, and certain supplies. Additionally, we have replacement parts in inventory, which are deemed critical to the operating equipment and may also have extended lead times should the part fail and need to be replaced. Inventories are valued at the lower of cost or market with cost determined by the first-in, first-out method.
	Property and Equipment
	Property and equipment expenditures are capitalized and depreciated using the straight-line method over the estimated useful lives of the assets for financial statement purposes, while accelerated depreciation methods are principally used for income tax purposes. Generally, asset lives range from ten to forty years for buildings (including improvements and asset retirement costs) and three to seven years for office furniture and equipment, vehicles, and decontamination and processing equipment. Leasehold improvements are capitalized and amortized over the lesser of the term of the lease or the life of the asset. Maintenance and repairs are charged directly to expense as incurred. The cost and accumulated depreciation of assets sold or retired are removed from the respective accounts, and any gain or loss from sale or retirement is recognized in the accompanying consolidated statements of operations. Renewals and improvements, which extend the useful lives of the assets, are capitalized.
	In accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 360, “Property, Plant, and Equipment”, long-lived assets, such as property, plant and equipment, and purchased intangible assets subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of are separately presented in the balance sheet and reported at the lower of the carrying amount or fair value less costs to sell, and are no longer depreciated. The assets and liabilities of a disposal group classified as held for sale would be presented separately in the appropriate asset and liability sections of the balance sheet.
	Our PFSG subsidiary is within our discontinued operations and is held for sale. On August 14, 2013, our PFSG facility incurred fire damage which has left it non-operational. The Company has recorded $723,000 and $130,000 in impairment charges for fixed assets related to the fire for the years ended December 31, 2014 and 2013, respectively.
	Our depreciation expense totaled approximately $3,602,000 and $3,381,000 in 2014 and 2013, respectively.
	Intangible Assets
	Intangible assets consist primarily of the recognized value of the permits required to operate our business and goodwill (as in previous years), or the cost of purchased businesses in excess of the estimated fair value of net identifiable assets acquired. As of December 31, 2014, we have no goodwill remaining. In connection with the sale of our SYA subsidiary on July 29, 2014, the Company recorded a goodwill impairment charge of $380,000 during the second quarter of 2014 for the SYA reporting unit. The Company fully impaired the goodwill for each of our Treatment, SEC, and CH Plateau Remediation Company (“CHPRC”) reporting units totaling approximately $27,856,000 during 2013. We continually reevaluate the propriety of the carrying amount of permits and goodwill (when applicable) to determine whether current events and circumstances warrant adjustments to the carrying value.
	Indefinite-lived intangible assets are not amortized but are reviewed for impairment annually as of October 1, or when events or changes in the business environment indicate that the carrying value may be impaired. If the fair value of the asset is less than the carrying amount, we perform a quantitative test to determine the fair value. The impairment loss, if any, is measured as the excess of the carrying value of the asset over its fair value. Significant judgments are inherent in these analyses and include assumptions for, among others factors, forecasted revenue, gross margin, growth rate, operating income, timing of expected future cash flows, and the determination of appropriate long term discount rates.
	We performed impairment testing of our permits related to our Treatment reporting unit as of October 1, 2014 and 2013 and determined no impairment existed.
	Intangible assets that have definite useful lives are amortized using the straight-line method over the estimated useful lives (with the exception of customer relationships which are amortized using an accelerated method) and are excluded from our annual intangible asset valuation review conducted as of October 1. The Company has one definite-lived permit which was excluded from our annual impairment review as noted above. The net carrying value of this one definite-lived permit as of December 31, 2014, was approximately $227,000. Definite-lived intangible assets are also tested for impairment whenever events or changes in circumstances suggest impairment might exist.
	Research and Development (“R&D”)
	Operational innovation and technical know-how is very important to the success of our business. Our goal is to discover, develop, and bring to market innovative ways to process waste that address unmet environmental needs and to develop new company service offerings. The Company conducts research internally and also through collaborations with other third parties. Research and development costs consist primarily of employee salaries and benefits, laboratory costs, third party fees, and other related costs associated with the development and enhancement of new potential waste treatment processes and are charged to expense when incurred in accordance with FASB ASC Topic 730, “Research and Development.” The Company’s R&D costs include R&D costs for our Perma-Fix Medical S.A., which primarily is to provide a financing vehicle for the development and marketing of its medical isotope (Tc-99m) technology used in medical diagnostic testing.
	Accrued Closure Costs and Asset Retirement Obligations (“ARO”)
	Accrued closure costs represent our estimated environmental liability to clean up our facilities as required by our permits, in the event of closure. ASC 410, “Asset Retirement and Environmental Obligations” requires that the discounted fair value of a liability for an ARO be recognized in the period in which it is incurred with the associated ARO capitalized as part of the carrying cost of the asset. The recognition of an ARO requires that management make numerous estimates, assumptions and judgments regarding such factors as estimated probabilities, timing of settlements, material and service costs, current technology, laws and regulations, and credit adjusted risk-free rate to be used. This estimate is inflated, using an inflation rate, to the expected time at which the closure will occur, and then discounted back, using a credit adjusted risk free rate, to the present value. ARO’s are included within buildings as part of property and equipment and are depreciated over the estimated useful life of the property. In periods subsequent to initial measurement of the ARO, the Company must recognize period-to-period changes in the liability resulting from the passage of time and revisions to either the timing or the amount of the original estimate of undiscounted cash flow. Increases in the ARO liability due to passage of time impact net income as accretion expense, which is included in cost of goods sold. Changes in costs resulting from changes or expansion at the facilities require adjustment to the ARO liability calculated and are capitalized and charged as depreciation expense, in accordance with the Company’s depreciation policy.
	Income Taxes
	Income taxes are accounted for in accordance with ASC 740, “Income Taxes.” Under ASC 740, the provision for income taxes is comprised of taxes that are currently payable and deferred taxes that relate to the temporary differences between financial reporting carrying values and tax bases of assets and liabilities. Deferred tax assets and liabilities are measured using enacted income tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Any effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.
	ASC 740 requires that deferred income tax assets be reduced by a valuation allowance if it is more likely than not that some portion or all of the deferred income tax assets will not be realized. The Company evaluates the realizability of its deferred income tax assets, primarily resulting from impairment loss and net operating loss carryforwards, and adjusts its valuation allowance, if necessary. Once the Company utilizes its net operating loss carryforwards or reverses the related valuation allowance it has recorded on these deferred tax assets, the Company would expect its provision for income tax expense in future periods to reflect an effective tax rate that will be significantly higher than past periods.
	ASC 740 sets out a consistent framework for preparers to use to determine the appropriate recognition and measurement of uncertain tax positions. ASC 740 uses a two-step approach wherein a tax benefit is recognized if a position is more-likely-than-not to be sustained. The amount of the benefit is then measured to be the highest tax benefit which is greater than 50% likely to be realized. ASC 740 also sets out disclosure requirements to enhance transparency of an entity’s tax reserves. The Company recognizes accrued interest and income tax penalties related to unrecognized tax benefits as a component of income tax expense.
	The Company reassesses the validity of our conclusions regarding uncertain income tax positions on a quarterly basis to determine if facts or circumstances have arisen that might cause us to change our judgment regarding the likelihood of a tax position’s sustainability under audit.
	Foreign Currency
	The Company’s foreign subsidiaries include Perma-Fix Environmental Services UK Limited (“Perma-Fix UK Limited”), Perma-Fix Canada, Inc. and Perma-Fix Medical S.A. Assets and liabilities are translated to U.S. dollars at the exchange rate in effect at the balance sheet date and revenue and expenses at the average exchange rate for the period. Foreign currency translation adjustments for these subsidiaries are accumulated as a separate component of accumulated other comprehensive income (loss) in stockholders’ equity. Gains and losses resulting from foreign currency transactions are recognized in the consolidated statements of operations.
	Concentration Risk
	The Company performed services relating to waste generated by the federal government, either directly as a prime contractor or indirectly as a subcontractor to the federal government, representing approximately $34,780,000 or 60.9% of total revenue from continuing operations during 2014, as compared to $47,557,000 or 63.9% of total revenue from continuing operations during 2013.
	The following customers accounted for 10% or more of the total revenues generated from continuing operations for twelve months ended December 31, 2014 and 2013:
			Total		% of Total
	Customer	Year	Revenue		Revenue
	United States Enrichment Corporation ("USEC")	2014	$	10,272,000		18	%
		2013	$	2,037,000		2.7	%
	CH Plateau Remediation Company ("CHPRC")	2014	$	5,762,000		10.1	%
		2013	$	19,922,000		26.8	%
	As revenues are event/project based where the completion of one contract with a specific customer may be replaced by another contract with a different customer from year to year, the Company does not believe the loss of one specific customer from one year to the next will generally have a material adverse effect on operations and financial condition.
	Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash and cash equivalents and accounts receivable. The Company maintains cash and cash equivalents with high quality financial institutions, which may exceed Federal Deposit Insurance Corporation (“FDIC”) insured amounts from time to time. Concentration of credit risk with respect to accounts receivable is limited due to the Company's large number of customers and their dispersion throughout the United States as well as with the significant amount of work that we perform for the federal government as discussed above.
	The Company has one customer whose net oustanding net receivable balance represented 13.4% and 13.9% of the Company’s total consolidated net accounts receivable at December 31, 2014 and 2013, respectively.
	Gross Receipts Taxes and Other Charges
	ASC 605-45, “Revenue Recognition – Principal Agent Consideration” provides guidance regarding the accounting and financial statement presentation for certain taxes assessed by a governmental authority. These taxes and surcharges include, among others, universal service fund charges, sales, use, waste, and some excise taxes. In determining whether to include such taxes in its revenue and expenses, the Company assesses, among other things, whether it is the primary obligor or principal taxpayer for the taxes assessed in each jurisdiction where the Company does business. As the Company is merely a collection agent for the government authority in certain of our facilities, the Company records the taxes on a net bases and excludes them from revenue and cost of services.
	Revenue Recognition
	Treatment Segment revenues. The processing of mixed waste is complex and may take several months or more to complete; as such, the Treatment Segment recognizes revenues using a performance based methodology with its measure of progress towards completion determined based on output measures consisting of milestones achieved and completed. The Treatment Segment has waste tracking capabilities, which it continues to enhance, to allow for better matching of revenues earned to the processing phases achieved. The revenues are recognized as each of the following three processing phases are completed: receipt, treatment/processing and shipment/final disposal. However, based on the processing of certain waste streams, the treatment/processing and shipment/final disposal phases may be combined as sometimes they are completed concurrently. As major processing phases are completed and the costs incurred, the Treatment Segment recognizes the corresponding percentage of revenue utilizing a proportional performance model. The Treatment Segment experiences delays in processing invoices due to the complexity of the documentation that is required for invoicing, as well as the difference between completion of revenue recognition milestones and agreed upon invoicing terms, which results in unbilled receivables. The timing differences occur for several reasons, partially from delays in the final processing of all wastes associated with certain work orders and partially from delays for analytical testing that is required after the waste is processed waste but prior to our release of the waste for disposal. As the waste moves through these processing phases and revenues are recognized, the correlating costs are expensed as incurred. Although the Treatment Segment uses its best estimates and all available information to accurately determine these disposal expenses, the risk does exist that these estimates could prove to be inadequate in the event the waste requires retreatment. Furthermore, should the waste be returned to the customer, the related receivables could be uncollectible; however, historical experience has not indicated this to be a material uncertainty.
	Services Segment revenues. Revenue includes services performed under time and material, fixed price, and cost-reimbursement contracts. Revenues and costs associated with fixed price contracts are recognized using the percentage of completion (efforts expended) method. The Services Segment estimates its percentage of completion based on attainment of project milestones. Revenues and costs associated with time and material contracts are recognized as revenue when earned and costs are incurred.
	Under cost reimbursement contracts, the Services Segment is reimbursed for costs incurred plus a certain percentage markup for indirect costs, in accordance with contract provisions. Costs incurred in excess of contract funding may be renegotiated for reimbursement. The Services Segment also earns a fee based on the approved costs to complete the contract. The Services Segment recognizes this fee using the proportion of costs incurred to total estimated contract costs.
	Contract costs include all direct labor, material and other non-labor costs and those indirect costs related to contract support, such as depreciation, fringe benefits, overhead labor, supplies, tools, repairs and equipment rental. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined. Changes in job performance, job conditions and estimated profitability, including those arising from contract penalty provisions and final contract settlements, may result in revisions to costs and income and are recognized in the period in which the revisions are determined.
	Self-Insurance
	The Company is self-insured for a significant portion of our group health. The Company estimates expected losses based on statistical analyses of historical industry data, as well as our own estimates based on the Company’s actual historical data to determine required self-insurance reserves. The assumptions are closely reviewed, monitored, and adjusted when warranted by changing circumstances. The estimated accruals for these liabilities could be affected if actual experience related to the number of claims and cost per claim differs from these assumptions and historical trends. Based on the information known on December 31, 2014, the Company believes it has provided adequate reserves for our self-insurance exposure. As of December 31, 2014 and 2013, self-insurance reserves were $397,000 and $473,000, respectively, and were included in Accrued expenses in the accompanying consolidated balance sheets. The total amounts expensed for self-insurance during 2014 and 2013 were $2,697,000, and $2,906,000, respectively, for our continuing operations.
	Stock-Based Compensation
	The Company accounts for stock-based compensation in accordance with ASC 718, “Compensation – Stock Compensation”. ASC 718 requires all stock-based payments to employees, including grants of employee stock options, to be recognized in the income statement based on their fair values. The Company uses the Black-Scholes option-pricing model to determine the fair-value of stock-based awards which requires subjective assumptions. Assumptions used to estimate the fair value of stock options granted include the exercise price of the award, the expected term, the expected volatility of the Company’s stock over the option’s expected term, the risk-free interest rate over the option’s expected term, and the expected annual dividend yield.
	The Company recognizes stock-based compensation expense using a straight-line amortization method over the requisite service period, which is the vesting period of the stock option grant. As ASC 718 requires that stock-based compensation expense be based on options that are ultimately expected to vest, our stock-based compensation expense is reduced by an estimated forfeiture rate. Our estimated forfeiture rate is generally based on historical trends of actual forfeitures. Forfeiture rates are evaluated, and revised as necessary.
	Comprehensive Income
The components of comprehensive income are net income and the effects of foreign currency translation adjustments.
Earnings Per Share
Basic earnings per share is calculated based on the weighted-average number of outstanding common shares during the applicable period. Diluted earnings per share is based on the weighted-average number of outstanding common shares plus the weighted-average number of potential outstanding common shares. Earnings per share is computed separately for each period presented.
The diluted loss per share calculations exclude options to purchase approximately 201,000 and 339,000 shares of common stock for the years ended December 31, 2014 and 2013, respectively, because their effect would have been antidilutive as a result of the net losses recorded in these periods.
Fair Value of Financial Instruments
Certain assets and liabilities are required to be recorded at fair value on a recurring basis, while other assets and liabilities are recorded at fair value on a nonrecurring basis.  Fair value is determined based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. The three-tier value hierarchy, which prioritizes the inputs used in the valuation methodologies, is:
Level 1—Valuations based on quoted prices for identical assets and liabilities in active markets.
Level 2—Valuations based on observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data.
Level 3—Valuations based on unobservable inputs reflecting the Company’s own assumptions, consistent with reasonably available assumptions made by other market participants.
Financial instruments include cash and restricted cash (Level 1), accounts receivable, accounts payable, and debt obligations (Level 3).  Credit is extended to customers based on an evaluation of a customer’s financial condition and, generally, collateral is not required. At December 31, 2014 and December 31, 2013, the fair value of the Company’s financial instruments approximated their carrying values.  The fair value of the Company’s revolving credit facility approximates its carrying value due to the variable interest rate. The carrying value of our subsidiary's preferred stock is not significantly different than its fair value.
Recently Adopted Accounting Standards
In April 2014, the FASB issued Accounting Standards Update (“ASU”) No. 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity.” ASU 2014-08, among other things, raises the threshold for disposals to qualify as discontinued operations. Under ASU 2014-08, a discontinued operation is (1) a component of an entity or group of components that has been disposed of by sale, disposed of other than by sale or is classified as held for sale that represents a strategic shift that has or will have a major effect on an entity’s operations and financial results or (2) an acquired business or nonprofit activity that is classified as held for sale on the date of the acquisition. ASU 2014-08 also requires additional disclosures for discontinued operations and new disclosures for individually material disposal transactions that do not meet the definition of a discontinued operation. This ASU is effective for annual periods beginning on or after December 15, 2014 and interim periods within that year. Early adoption of ASU 2014-08 was permitted but only for disposals (or classifications as held for sale) that were not reported in financial statements previously issued or available for issue. The Company early adopted ASU 2014-08 during the second quarter of 2014. On April 3, 2014, the Company’s Board of Directors (“Board”) approved management to pursue the sale of our wholly owned subsidiary, SYA. On July 29, 2014, the Company completed the divestiture of SYA. In accordance with ASU 2014-08, the divestiture of SYA is presented within our continuing operations. The sale of SYA did not represent a strategic shift that has had a major effect on the Company's operations and financial results as defined by ASU 2014-08.
In November 2014, the FASB issued ASU 2014-17, “Pushdown Accounting”. ASU 2014-17 provides companies with the option to apply pushdown accounting in its separate financial statements upon occurrence of an event in which an acquirer obtains control of the acquired entity. The election to apply pushdown accounting can be made either in the period in which the change of control occurred, or in a subsequent period. This ASU is effective as of November 18, 2014. The adoption of this ASU did not have an impact on the Company's results of operations, cash flows or financial position
Recently Issued Accounting Standards – Not Yet Adopted
In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606).” ASU 2014-09 provides a single, comprehensive revenue recognition model for all contracts with customers. The revenue guidance contains principles that an entity will apply to determine the measurement of revenue and timing of when it is recognized. The underlying principle is that an entity will recognize revenue to depict the transfer of goods or services to customers at an amount that the entity expects to be entitled to in exchange for those goods or services. The standard will be effective for the first interim period within annual reporting periods beginning after December 15, 2016 for public entities, with no early adoption permitted, and allows for either full retrospective adoption or modified retrospective adoption. The Company is still evaluating the potential impact of adopting this guidance on our financial statements.
In June 2014, the FASB issued ASU 2014-12, “Compensation Stock – Compensation (Topic 718).” ASU 2014-12 applies to all reporting entities that grant their employees share-based payments in which the terms of the award provide that a performance target that affects vesting could be achieved after the requisite service period. It requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition and follows existing accounting guidance for the treatment of performance conditions. The standard is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015, with early adoption permitted. The Company is still evaluating the potential impact of adopting this guidance on our financial statements.
In August 2014, the FASB issued ASU No. 2014-15, “Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern.” ASU 2014-15 requires management to assess an entity’s ability to continue as a going concern, and to provide related footnote disclosure in certain circumstances. The new standard will be effective for all entities in the first annual period ending after December 15, 2016. The Company is still evaluating the potential impact of adopting this guidance on our financial statements.
In November 2014, the FASB issued ASU, 2014-16, “Determining Whether the Host Contract in a Hybrid Financial Instrument Issued in the Form of a Share Is More Akin to Debt or to Equity.” ASU 2014-06 clarifies how current guidance should be interpreted in evaluating the economic characteristics and risks of a host contract in a hybrid financial instrument that is issued in the form of a share. Specifically, the amendments clarify that an entity should consider all relevant terms and features, including the embedded derivative feature being evaluated for bifurcation, in evaluating the nature of a host contract. The ASU is effective for fiscal years and interim periods beginning after December 15, 2015. The Company is still evaluating the potential impact of adopting this guidance on our financial statements.

Reclassifications [Text Block]	NOTE 3
	REVISION OF PRIOR PERIOD FINANCIAL STATEMENTS
	During the Company’s preparation of the 2014 income tax provision, the Company determined that certain deferred tax liabilities related to acquired indefinite-lived permits from the Company’s acquisition of our DSSI subsidiary in 2000 and our M&EC subsidiary in 2001 were not recorded. Upon adoption of Statement of Financial Accounting Standards No. 142, “Goodwill and Other Intangible Assets” by the Company in 2002 (now ASC 350, “Intangibles-Goodwill and Others”), the acquired permits were determined to be indefinite-lived intangible assets. As a result, deferred tax liabilities should have been established for these indefinite-lived intangible assets on January 1, 2002, with the offset being expense. Further, as these deferred tax liabilities relate to indefinite lived intangible assets, they cannot be utilized for purposes of offsetting deferred tax assets in evaluating the need for a deferred tax asset valuation allowance.
	In order to correct these errors, we recorded an adjustment to increase the 2013 opening balance of accumulated deficit in our Consolidated Statements of Stockholders’ Equity by $3,455,000. Due to rules requiring an allocation of valuation allowance to deferred tax assets, the correction of this error also resulted in an increase to deferred tax liabilities (long-term) of $3,915,000 and an increase to deferred tax assets (current) of $460,000 for a net deferred tax liability of $3,455,000 as of December 31, 2013.
	The Company considered the guidance in ASC 250, “Accounting Changes and Error Corrections; Staff Accounting Bulletin Topic 1:M, Materiality; and Topic 1:N, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements,” and concluded that the error was not material to previously issued financial statements. The resulting revision had no impact on the Company’s previously reported cash, Consolidated Statement of Operations, Consolidated Statement of Comprehensive Loss, and Consolidated Statements of Cash Flows as of and for the year ended December 31, 2013.
	The following table summarizes the impact of the revision on each affected line of the Company’s Consolidated Balance Sheet as of December 31, 2013:

Perma Fix Medical SA [Abstract]
Perma Fix Medical SA [Text Block]	NOTE 4
	PERMA-FIX MEDICAL S.A.
	On April 4, 2014, the Company completed the acquisition of a controlling interest in a Polish Company, a publicly traded shell company on the NewConnect (alternative share market run by the Warsaw Stock Exchange) in Poland and sold to the Polish shell all of the shares of Perma-Fix Medical Corporation, a Delaware corporation (“PF Medical”) organized by the Company (incorporated in January 2014). PF Medical’s only asset was and is a worldwide license granted by the Company to use, develop and market the new process and technology developed by the Company in the production of Technetium-99 or “Tc-99m” for medical diagnostic applications. Since the acquired shell company (now named as Perma-Fix Medical S.A.) does not meet the definition of a business under ASC 805, “Business Combinations”, the transaction was accounted for as a capital transaction. The primary purpose of PF Medical S.A. (which we own 64%) is to provide a financing vehicle for the development and marketing of its medical isotope (“Tc-99m”) technology used in medical diagnostic testing for potential use throughout the world.
	During August, 2014, PF Medical S.A. executed stock subscription agreements totaling approximately $2,357,000 for 250,000 shares of its Series E Common Stock to non-U.S. persons in an offshore private placement under Regulation S promulgated under the Securities Act of 1933, as amended (“Securities Act”). In connection with this transaction, as of December 31, 2014, PF Medical S.A. has received approximately $1,478,000 for 155,839 shares (before deduction for commissions and legal expenses relating to this offering of approximately $242,000). PF Medical S.A. further expects to receive approximately $636,000, prior to any commission, on or prior to July 31, 2015, for payment of 68,161 of such shares and another $243,000 by December 2015, for payment of the remaining 26,000 of such shares. The unpaid shares as of December 31, 2014 in this transaction were accounted for as subscription receivables and are offset against non-controlling interest. If PF Medical S.A. is not paid for the 68,161 shares on or prior to July 31, 2015, PF Medical S.A. has the option to have the purchaser of such shares transfer all of its rights, title and interest in such shares to PF Medical S.A. or for PF Medical S.A. be paid for the 68,161 shares with shares in another publicly traded company.

	Stock Option Plans
	Effective July 29, 2003, the Company adopted the 2003 Outside Directors Stock Plan (the “2003 Plan”), which was approved by our stockholders at the Annual Meeting of Stockholders on such date. The plan provides for the grant of an option to purchase up to 30,000 shares of Common Stock for each outside director upon initial election to the Board of Directors, and the grant of an option to purchase up to 12,000 shares of Common Stock upon each re-election. The options granted generally have a vesting period of six months from the date of grant, with an exercise price equal to the closing trade price on the date prior to grant date. The plan also provides for the issuance to each outside director a number of shares of Common Stock in lieu of 65% or 100% (based on option elected by each director) of the fee payable to the eligible director for services rendered as a member of the Board of Directors. The number of shares issued is determined at 75% of the market value as defined in the plan. At the Company’s Annual Meeting of Stockholders held on September 18, 2014, the Company’s stockholders approved the Third Amendment to the 2003 Outside Directors Stock Plan which increased the number of shares of our Common Stock authorized for issuance under the 2003 Plan from 600,000 to 800,000; (b) reduced proportionately the number of shares of Common Stock subject to the automatic option grant made to each eligible director upon initial election from 30,000 to 6,000 and the number of shares of Common Stock subject to automatic option grant made to each eligible director upon re-election from 12,000 to 2,400; and (c) allowed for such shares to be adjusted proportionally upon future stock splits or other share adjustment applicable to our Common Stock. On October 15, 2013, the Company effected a reverse stock split at a ratio of 1-for-5 of the Company’s then outstanding Common Stock and shares of Common Stock issuable upon exercise of the then outstanding stock options and warrants; however, pursuant the terms of the 2003 Plan, the number of shares of Common Stock which each Eligible Director can purchase under the automatic option granted upon initial election or re-election was not adjusted proportionately to give effect to the reverse stock split.
	Effective July 28, 2004, the Company adopted the 2004 Stock Option Plan, which was approved by our stockholders at the Annual Meeting of Stockholders on such date. The plan provides for the grants of options to selected officers and employees, including any employee who is also a member of the Board of Directors of the Company. A maximum of 400,000 (as automatically adjusted to the reverse stock split on October 15, 2013, pursuant to the plan) shares of our Common Stock are authorized for issuance under this plan in the form of either Incentive or Non-Qualified Stock Options (“ISOs” or “NQSOs”, respectively). The option grants under the plan are exercisable for a period of up to 10 years from the date of grant at an exercise price of not less than market price of the Common Stock at grant date. On July 28, 2014, the plan expired. No new options will be issued under this plan, but the options issued under this plan prior to the expiration date will remain in effect until their respectively maturity dates (which will be February 26, 2015).
	On April 28, 2010, the Company adopted the 2010 Stock Option Plan, which was approved by our stockholders at the Company’s Annual Meeting of Stockholders on September 29, 2010. The Plan authorizes an aggregate grant of 200,000 NQSOs and ISOs to officers and employees of the Company for the purchase of up to 200,000 shares of the Company’s Common Stock (as automatically adjusted to the reverse stock split on October 15, 2013, pursuant to the plan). The term of each stock option granted will be fixed by the Compensation Committee, but no stock option will be exercisable more than ten years after the grant date, or in the case of an incentive stock option granted to a 10% stockholder, five years after the grant date. The exercise price of any incentive stock option granted under the Plan to an individual who is not a 10% stockholder at the time of the grant will not be less than the fair market value of the shares at the time of the grant, and the exercise price of any incentive stock option granted to a 10% stockholder shall not be less than 110% of the fair market value at the time of grant. The exercise price of any NQSOs granted under the Plan will not be less than the fair market value of the shares at the time of grant.
	No employees exercised options during 2014 and 2013. During 2014, we issued a total of 2,577 shares of our Common Stock upon exercise of 2,577 NQSOs by an outside director from the 2003 Outside Director Stock Plan, at exercise price of $2.79 per share which resulted in total proceeds of approximately $7,200.
	We issued a total of 67,335 and 69,041 shares of our Common Stock in 2014 and 2013, respectively, under our 2003 Outside Directors Stock Plan to our outside directors as compensation for serving on our Board of Directors (“Board”). As a member of the Board, each director elects to receive either 65% or 100% of the director’s fee in shares of our Common Stock. The number of shares received is calculated based on 75% of the fair market value of our Common Stock determined on the business day immediately preceding the date that the quarterly fee is due. The balance of each director’s fee, if any, is payable in cash.
	Summary of the status of options under the Company’s Stock Option Plans as of December 31, 2014 and 2013, and changes during the years ending on those dates is presented below:

	Preferred Share Rights Plan
	In May 2008, the Company adopted a preferred share rights plan (the “Rights Plan”), designed to ensure that all of our stockholders receive fair and equal treatment in the event of a proposed takeover or abusive tender offer.
	In general, under the terms of the Rights Plan, subject to certain limited exceptions, if a person or group acquires 20% or more of our Common Stock or a tender offer or exchange offer for 20% or more of our Common Stock is announced or commenced, our other stockholders may receive upon exercise of the rights (the “Rights”) issued under the Rights Plan the number of shares our Common Stock or of one-one hundredths of a share of our Series A Junior Participating Preferred Stock, par value $.001 per share, having a value equal to two times the purchase price of the Right. In addition, if we are acquired in a merger or other business combination transaction in which we are not the survivor or more than 50% of our assets or earning power is sold or transferred, then each holder of a Right (other than the acquirer) will thereafter have the right to receive, upon exercise, common stock of the acquiring company having a value equal to two times the purchase price of the Right. The initial purchase price of each Right was $13.00, subject to adjustment and adjustment for the reverse stock split.
	The Rights will cause substantial dilution to a person or group that attempts to acquire us on terms not approved by our board of directors. The Rights may be redeemed by us at $0.001 per Right at any time before any person or group acquires 20% or more of our outstanding Common Stock. The Rights expire on May 2, 2018.
	Warrants and Capital Stock Issuance for Debt
	As of December 31, 2014, we have two Warrants outstanding which provide for the purchase of up to an aggregate of 70,000 shares of the Company’s Common Stock at $2.23 per share. The two Warrants were issued on August 2, 2013, as consideration of a $3,000,000 loan received by the Company from Messrs. William N. Lampson and Robert L. Ferguson (the “Lenders”). Each Warrant provides for the Lender to purchase up to 35,000 shares of the Company’s Common Stock at an exercise price of $2.23 per share. The Warrants are exercisable six months from August 2, 2013 and expire on August 2, 2016. The Company also issued 90,000 shares of the Company’s Common Stock to the Lenders. See Note 9 – “Long-Term Debt – Promissory Note and Installment Agreement” for further information and accounting treatment of the Warrants and Common Stock.
	Shares Reserved
	At December 31, 2014, we have reserved approximately 309,023 shares of Common Stock for future issuance under all of the option and warrant arrangements.
	Stock Based Compensation
	We follow ASC 718 to account for stock-based compensation. ASC 718 requires all stock-based payments to employees, including grants of employee stock options, to be recognized in the statement of operations based on their fair values.
	As discussed above, the Company has certain stock option plans which it awards NQSOs and ISOs to employees, officers, and outside directors. Stock options granted to employees have a six year contractual term with one-third yearly vesting over a three year period. Stock options granted to outside directors have a ten year contractual term with vesting period of six months.
	On July 10, 2014, the Company granted an aggregate of 55,000 ISOs from the Company’s 2010 Stock Option Plan to certain employees, of which 45,000 ISOs were granted to the Company’s Chief Operating Officer (who was appointed March 20, 2014). The 55,000 ISOs granted were for a contractual term of six years with one-third yearly vesting over a three year period. The exercise price of the ISOs was $5.00 per share, which was equal to our closing stock price as reported on Nasdaq on the date of grant.
	On September 18, 2014, the Company granted an aggregate of 16,800 NQSOs from the Company’s 2003 Outside Directors Stock Plan to our seven re-elected directors at our Annual Meeting of Stockholders held on September 18, 2014. The NQSOs granted were for a contractual term of ten years with a vesting period of six months. The exercise price of the NQSOs was $3.70 per share, which was equal to our closing stock price the day preceding the grant date, pursuant to the 2003 Outside Directors Stock Plan.
	As of December 31, 2014, the Company had an aggregate of 70,000 employee stock options outstanding (from the 2004 and 2010 Stock Option Plans), of which 15,000 are vested. The weighted average exercise price of the 15,000 outstanding and fully vested employee stock options is $7.10 with a remaining weighted contractual life of 0.2 years. Additionally, the Company had an aggregate of 169,023 outstanding director stock options (from the 2003 Outside Directors Stock Plans), of which 152,223 are vested. The weighted average exercise price of the 152,223 outstanding and fully vested director stock options is $9.35 with a remaining weighted contractual life of 4.6 years.
	The Company estimates fair value of stock options using the Black-Scholes valuation model. Assumptions used to estimate the fair value of stock options granted include the exercise price of the award, the expected term, the expected volatility of the Company’s stock over the option’s expected term, the risk-free interest rate over the option’s expected term, and the expected annual dividend yield. The fair value of the options granted during in 2014 and 2013 and the related assumptions used in the Black-Scholes option model used to value the options granted were as follows (No options were granted to employees during 2013):
		Employee Stock Option Granted For Year Ended 2014
Weighted-average fair value per share		$	2.88
Risk -free interest rate (1)			1.91	%
Expected volatility of stock (2)			61.84	%
Dividend yield		None
Expected option life (years) (3)		6
		Outside Director Stock Options Granted
		For Year Ended
		2014			2013
Weighted-average fair value per share		$	2.73		$	2.06
Risk -free interest rate (1)			2.63	%		2.66% - 2.92	%
Expected volatility of stock (2)			59.59	%		58.88% - 59.76	%
Dividend yield		None			None
Expected option life (in years) (3)			10			10
(1) The risk-free interest rate is based on the U.S. Treasury yield in effect at the grant date over the expected term of the option.
(2) The expected volatility is based on historical volatility from our traded Common Stock over the expected term of the option.
(3) The expected option life is based on historical exercises and post-vesting data.
The following table summarizes stock-based compensation recognized for the fiscal year 2014 and 2013.
		Year Ended
		2014			2013
Employee Stock Options		$	(14,000	)	$	80,000
Director Stock Options			48,000			45,000
Total		$	34,000		$	125,000
The Company recognized stock-based compensation expense using a straight-line amortization method over the requisite service period, which is the vesting period of the stock option grant. ASC 718 requires that stock based compensation expense be based on options that are ultimately expected to vest. ASC 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The Company has generally estimated forfeiture rates based on historical trends of actual forfeitures. When actual forfeitures vary from our estimates, the Company recognizes the difference in compensation expense in the period the actual forfeitures occur or when options vest. The total stock-based compensation expense for the twelve months ended December 31, 2014 included a reduction in expense of approximately $54,000 resulting from the forfeiture of options by Mr. Jim Blankenhorn, our previous COO, who voluntarily resigned from the Company effective March 28, 2014. The COO was granted an option from the Company’s 2010 Stock Option Plan on July 25, 2011, which provided for the purchase of up to 60,000 shares of the Company’s Common Stock at $7.85 per share. The options had a six year contractual term with one-third yearly vesting over a three year period. As of December 31, 2014, the Company has approximately $145,000 of total unrecognized compensation cost related to unvested options, of which $73,000 is expected to be recognized in 2015, $53,000 in 2016, with the remaining $19,000 in 2017.

	Divestiture of SYA
	On July 29, 2014, the Company completed the sale of our wholly-owned subsidiary, SYA. SYA was a professional engineering and environmental consulting services company and was included in the Company’s Services Segment. In accordance with ASU 2014-08, the divestiture of SYA has been reported in continuing operations for all periods presented. The purchaser of SYA paid approximately $1,300,000 for 100% of the capital stock and $60,000 as an adjustment to the purchase price for excess working capital with $50,000 of such consideration placed in escrow for a period of one year to cover any claims by the purchaser for indemnification for certain limited types of losses incurred by the purchaser following the closing.  The proceeds received were used to pay down our revolver and used for working capital. As of December 31, 2014, expenses related to the sale of SYA totaled approximately $96,000. The Company recorded a loss on the sale of SYA of approximately $53,000 (net of taxes of $0), which included a final excess working capital adjustment of approximately $42,000. The loss on the sale of $53,000 was included in “other” expense on our Consolidated Statements of Operations. In 2013, SYA had net revenues of $2,564,736 and a net loss of $621,288.
	Discontinued Operations
	The Company’s discontinued operations consist of all our subsidiaries included in our Industrial Segment: (1) subsidiaries divested in 2011 and prior, (2) two previously closed locations, and (3) our PFSG facility.
	On August 14, 2013, our PFSG facility incurred fire damage which left it non-operational. Certain equipment and portions of the building structures were damaged, which resulted in the Company recognizing an impairment charge of fixed assets for approximately $130,000. The Company carries general liability, pollution, property and business interruption, and workers compensation insurance with a maximum deductible of approximately $300,000. Total incurred costs through December 31, 2013 relating to the fire, inclusive of the impairment charge, was $6,859,000. For the year ended December 31, 2013, the Company had received $3,664,000 of insurance proceeds and recorded an insurance recovery receivable of $2,995,000 as we had determined that receipt of reimbursement of these expenses from our insurer was probable in accordance with its insurance policies.
	On June 20, 2014, the Company entered into a settlement agreement and release with one of its insurance carriers, resulting in receipt of approximately $3,850,000 in insurance settlement proceeds, which was used to pay down the Company’s Revolving Credit facility. On November 10, 2014, the Company received approximately $391,000 from another insurance carrier. Additionally, $1,500,000 of insurance proceeds were paid directly to the vendors working on the clean-up of the facility.
	The table below shows the total costs incurred and insurance proceeds received through December 31, 2014 relating to the fire:
		Property & Equipment			Business Interruption and Other			Total
	Costs incurred through December 31, 2014	$	4,507,000		$	4,096,000		$	8,603,000

	(1) Inclusive of $1,500,000 paid directly to vendors
	In 2014, the Company elected not to rebuild the PFSG facility, which resulted in a triggering event under ASC 360. Based on our long-lived asset impairment test, the Company concluded that tangible asset impairments existed for PFSG and therefore recorded approximately $723,000 of asset impairment charges for the twelve months ended December 31, 2014, which is included in “Income (loss) from discontinued operations, net of taxes” in the Consolidated Statements of Operations. No remaining intangible assets exist at PFSG at December 31, 2014. The Company continues to market our PFSG facility for sale.
	The following table summarizes the results of discontinued operations for the years ended December 31, 2014 and 2013. Income tax expense for 2013 included a charge to tax expense of approximately $1,164,000 to provide a full valuation allowance on our net deferred tax assets.

Environmental Liabilities
We have four remediation projects, which are currently in progress at our Perma-Fix of Dayton, Inc. (“PFD”), Perma-Fix of Memphis, Inc. (“PFM” – closed location), PFSG, and Perma-Fix of Michigan, Inc. (“PFMI” – closed location) subsidiaries. The Company divested PFD in 2008; however, the environmental liability of PFD was retained by the Company upon the divestiture of PFD. These remediation projects principally entail the removal/remediation of contaminated soil and, in most cases, the remediation of surrounding ground water. All of the remedial clean-up projects in question were an issue for that facility for years prior to our acquisition of the facility and were recognized pursuant to a business combination and recorded as part of the purchase price allocation to assets acquired and liabilities assumed. Three of the facilities (PFD, PFM, and PFSG) are Resource Conservation and Recovery Act (“RCRA”) permitted facilities, and as a result, the remediation activities are closely reviewed and monitored by the applicable state regulators.
At December 31, 2014, we had total accrued environmental remediation liabilities of $1,016,000, of which $728,000 is recorded as a current liability, which reflects a decrease of $15,000 from the December 31, 2013 balance of $1,031,000. The net decrease of $15,000 represents payments on remediation projects at the PFSG location. The December 31, 2014 current and long-term accrued environmental liabilities at December 31, 2014 are summarized as follows (in thousands):

	Revolving Credit and Term Loan Agreement
	The Company entered into an Amended and Restated Revolving Credit, Term Loan and Security Agreement, dated October 31, 2011, (“Agreement”), with PNC Bank, National Association (“PNC”), acting as agent and lender. The Agreement, as amended (“Amended Loan Agreement”), provides us with the following Credit Facility: (a) up to $12,000,000 revolving credit facility (which was reduced from $18,000,000 pursuant to Amendment 4, dated April 14, 2014.) (“Revolving Credit”), subject to the amount of borrowings based on a percentage of eligible receivables (as defined) and (b) a term loan (“Term Loan”) of $16,000,000, which requires monthly installments of approximately $190,000 (based on a seven-year amortization). As a result of the reduction in the maximum borrowing Revolving Credit noted above, the Company recorded approximately $37,000 in loss on debt modification (included in interest expense) during the second quarter of 2014 in accordance with ASC 470-50, “Debt – Modification and Extinguishment.”
	In addition to the reduction to our Revolving Credit facility, Amendment 4 also waived the Company’s fixed charge coverage ratio testing requirement for the first quarter of 2014, revised the methodology in calculating the Company’s quarterly fixed charge coverage ratio for the second to fourth quarters of 2014 and changed the minimum quarterly fixed charge coverage ratio requirement of 1:25 to 1:00 to 1:15 to 1:00 in 2014, among other things. As a condition of the Amendment 4, we agreed to pay PNC a fee of $30,000 which is being amortized over the remaining term of the Amended Loan Agreement.
	On July 25, 2014, the Company entered into Amendment 5 to the Amended Loan Agreement with PNC. This Amendment added our Perma-Fix of Canada, Inc. subsidiary as a guarantor under our credit facility. On July 28, 2014, the Company entered into Amendment 6 to the Amended Loan Agreement. This Amendment authorized the Company to sell our SYA subsidiary, released a hold by PNC which allows the Company to use the $3,850,000 insurance settlement proceeds received on June 30, 2014 by our PFSG subsidiary for working capital purposes but placed an indefinite reduction on our borrowing availability by $1,500,000. As a condition of Amendment 6, we agreed to pay PNC a fee of $15,000, which is being amortized over the term of the Amended Loan Agreement. All other terms of the Amended Loan Agreement remain principally unchanged.
	The Amended Loan Agreement terminates as of October 31, 2016, unless sooner terminated. We may terminate the Amended Loan Agreement upon 90 days’ prior written notice and upon payment in full of our obligations under the Amended Loan Agreement. No early termination fee shall apply if we pay off our obligations under the Amended Loan Agreement after October 31, 2013.
	Our Credit Facility with PNC contains certain financial covenants, along with customary representations and warranties. A breach of any of these financial covenants, unless waived by PNC, could result in a default under our credit facility allowing our lender to immediately require the repayment of all outstanding debt under our credit facility and terminate all commitments to extend further credit. Our Amended Loan Agreement prohibits us to declare, pay, or make any dividend distribution on any shares of our Common Stock or Preferred Stock. As discussed above, the fixed charge coverage ratio requirement for the first quarter of 2014 was waived by PNC. The Company met its fixed charge coverage ratio in each of the second to fourth quarters of 2014; however, if the Company fails to meet the minimum quarterly fixed charge coverage ratio requirement in any of the quarters in 2015 and PNC does not waive the non-compliance or further revise our covenant so that the Company is in compliance, our lender could accelerate the repayment of borrowings under our Credit Facility. In the event that our lender accelerates the payment of our borrowings, the Company may not have sufficient liquidity to repay our debt under our Credit Facility and other indebtedness.
	As of December 31, 2014, the availability under our revolving credit was $7,402,000, based on our eligible receivables and includes the indefinite reduction of borrowing availability of $1,500,000 as discussed above.
	Promissory Notes and Installment Agreements
	On February 12, 2013, the Company entered into an unsecured promissory note (“the new note”) with Timios National Corporation (“TNC” and formerly known as Homeland Security Capital Corporation) in the principal amount of approximately $230,000 as a result of a settlement with TNC in connection with certain claims that the Company asserted against TNC for breach of certain representations and covenant subsequent to our acquisition of Safety & Ecology Holdings Corporation and its subsidiaries (collectively known as Safety and Ecology Corporation or “SEC”) from TNC on October 31, 2011 (See payment terms of this promissory note in the table above). The new note was entered into as a result of the settlement in which a previously issued promissory note (with principal balance of $1,460,000 at February 12, 2013) that the Company entered into with TNC as partial consideration of the purchase price of SEC was cancelled and terminated and replaced with the new note. The new note provides the Company the right to prepay such at any time without interest or penalty.
	In the event of default of the new note payable to TNC by the Company, TNC has the option to convert the unpaid portion of the new note into a number of whole shares of the Company’s restricted Common Stock. The number of shares of the Company’s restricted Common Stock issuable is determined by the principal amount owing under the new note at the time of default plus all accrued and unpaid interest and expenses (as defined) divided by the average of the closing price per share of the Company’s Common Stock as reported by the primary national securities exchange on which the Company’s Common Stock is traded during the 30 consecutive trading day period ending on the trading day immediately prior to receipt by the Company of TNC’s written notice of its election to receive the Company’s restricted Common Stock as a result of the event of default by the Company, with the number of shares of the Company’s Common Stock issuable upon such default subject to certain limitations.
	On August 2, 2013, the Company completed a lending transaction with Messrs. Robert Ferguson and William Lampson (“collectively, the “Lenders”), whereby the Company borrowed from the Lenders the sum of $3,000,000 pursuant to the terms of a Loan and Security Purchase Agreement and promissory note (the “Loan”) (See payment terms of this promissory note in the table above). The Lenders are stockholders of the Company, having received shares of our Common Stock in connection with the acquisition of our PFNWR subsidiary in June 2007. The proceeds from the Loan were used for general working capital purposes. In connection with this Loan, the Lenders entered into a Subordination Agreement dated August 2, 2013, with the Company’s Credit Facility lender, whereby the Lenders agreed to subordinate payment under the Loan, and agreed that the Loan will be junior in right of payment to the Credit Facility in the event of default or bankruptcy or other insolvency proceeding by the Company. As consideration for the Company receiving the Loan, the Company issued a Warrant to each Lender to purchase up to 35,000 shares of the Company’s Common Stock at an exercise price based on the closing price of the Company’s Common Stock at the closing of the transaction which was determined to be $2.23. The Warrants are exercisable six months from August 2, 2013 and expire on August 2, 2016. The fair value of the Warrants was estimated to be approximately $59,000 using the Black-Scholes option pricing model with the following assumptions: 55.54% volatility, risk free interest rate of .59%, an expected life of three years and no dividends. As further consideration for the Loan, the Company also issued an aggregate 90,000 shares of the Company’s Common Stock, with each Lender receiving 45,000 shares. The Company determined the fair value of the 90,000 shares of Common Stock to be approximately $200,000 which was based on the closing price of the stock of $2.23 per share on August 2, 2013. The fair value of the Warrants and Common Stock and the related closing fees incurred from the transaction were recorded as a debt discount, which is being amortized using the effective interest method over the term of the loan as interest expense – financing fees. Mr. Robert Ferguson serves as an advisor to the Company’s Board of Directors (see Note 16 – “Related Party Transaction – Mr. Robert Ferguson” for further information on Mr. Ferguson).
	In the event of default of the promissory note by the Company, the Lenders have the option to receive a cash payment equal to the amount of the unpaid principal balance plus all accrued and unpaid interest (“Payoff Amount”), or the number of whole shares of the Company’s Common Stock equal to the Payoff Amount divided by the closing bid price of the Company’s Common Stock on the date immediately prior to the date of default of the promissory note, as reported by the primary national securities exchange on which the Company’s Common Stock is traded. The maximum number of payoff shares is restricted to less than 20% of the outstanding equity.

	ACCRUED CLOSURE COSTS AND ASSET RETIREMENT OBLIGATIONS (“ARO”)
	Accrued closure costs represent our estimated environmental liability to clean up our fixed-based regulated facilities as required by our permits, in the event of closure. Changes to reported closure liabilities for the years ended December 31, 2014 and 2013, were as follows:

	Accretion expense		286
	Balance as of December 31, 2014	$	5,508
	The adjustment in 2013 was made principally to record the obligation using appropriate discount rates.  The obligations were previously based on undiscounted values.  The associated assets were also adjusted to reflect this change.  The net impact of the adjustment to pre-tax loss from operations was approximately ($448,000) in 2013.
	The reported closure asset or ARO, is reported as a component of “Net Property and equipment” in the Consolidated Balance Sheet for the years ended December 31, 2014 and 2013 as follows:
	Amounts in thousands
	Balance as of December 31, 2012	$	9,080

	Income tax expense (benefit)		$	417			$	(625	)
	The provision for income taxes is determined in accordance with ASC 740, “Income Taxes”. Deferred income tax assets and liabilities are recognized for future tax consequences attributed to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred income tax assets and liabilities are measured using enacted income tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Any effect on deferred income tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.
	The Company regularly assesses the likelihood that the deferred tax asset will be recovered from future taxable income. The Company considers projected future taxable income and ongoing tax planning strategies, then records a valuation allowance to reduce the carrying value of the net deferred income taxes to an amount that is more likely than not to be realized. In 2014 and 2013, we determined that it was more likely than not that approximately $7,896,000 and $8,182,000, respectively, of deferred income tax assets would not be realized, and as such, a full valuation allowance was applied against those deferred income tax assets. Our valuation allowance increased by $216,000 and $1,415,000 for the years ended December 31, 2014 and 2013, respectively.
	We have estimated net operating loss carryforwards (NOLs) for federal and state income tax purposes of approximately $5,553,000 and $50,224,000, respectively, as of December 31, 2014. These net operating losses can be carried forward and applied against future taxable income, if any, and expire in various amounts starting in 2021. However, as a result of various stock offerings and certain acquisitions, which in the aggregate constitute a change in control, the use of these NOLs will be limited under the provisions of Section 382 of the Internal Revenue Code of 1986, as amended. Additionally, NOLs may be further limited under the provisions of Treasury Regulation 1.1502-21 regarding Separate Return Limitation Years.
	The Company accounts for uncertainties in income taxes pursuant to ASC 740. A reconciliation of the beginning and ending amount of our unrecognized tax expense is summarized as follows (in thousands):
		2014			2013
	Balances at beginning of year	$	180		―

	The tax years 2012 and 2013 remain open to examination by taxing authorities in the jurisdictions in which the Company operates.
	As of December 31, 2014 and 2013, the Company had approximately $85,000 and $183,000 of federal income tax payable, respectively.

	COMMITMENTS AND CONTINGENCIES
	Hazardous Waste
	In connection with our waste management services, we handle both hazardous and non-hazardous waste, which we transport to our own, or other, facilities for destruction or disposal. As a result of disposing of hazardous substances, in the event any cleanup is required, we could be a potentially responsible party for the costs of the cleanup notwithstanding any absence of fault on our part.
	Legal Matters
	In the normal course of conducting our business, we are involved in various litigation. We are not a party to any litigation or governmental proceeding which our management believes could result in any judgments or fines against us that would have a material adverse effect on our financial position, liquidity or results of future operations.
	Insurance
	The Company has a 25-year finite risk insurance policy entered into in June 2003 with American International Group, Inc. (“AIG”), which provides financial assurance to the applicable states for our permitted facilities in the event of unforeseen closure. The policy, as amended, provides for a maximum allowable coverage of $39,000,000 and has available capacity to allow for annual inflation and other performance and surety bond requirements. All of the required payments for this finite risk insurance policy, as amended, were made by 2012. As of December 31, 2014, our financial assurance coverage amount under this policy totaled approximately $38,675,000. The Company has recorded $15,429,000 in our sinking fund related to the policy noted above in other long term assets on the accompanying consolidated balance sheets, which includes interest earned of $958,000 on the sinking fund as of December 31, 2014. Interest income for twelve months ended December 31, 2014, was approximately $20,000. If the Company so elects, AIG is obligated to pay us an amount equal to 100% of the sinking fund account balance in return for complete release of liability from both us and any applicable regulatory agency using this policy as an instrument to comply with financial assurance requirements.
	In August 2007, the Company entered into a second finite risk insurance policy for our PFNWR facility with AIG. The policy provided an initial $7,800,000 of financial assurance coverage with an annual growth rate of 1.5%, which at the end of the four year term policy, provides maximum coverage of $8,200,000. The Company has made all of the required payments on this policy. As of December 31, 2014, the Company has recorded $5,905,000 in our sinking fund related to this policy in other long term assets on the accompanying consolidated balance sheets, which includes interest earned of $205,000 on the sinking fund as of December 31, 2014. Interest income for the twelve months ended December 31, 2014 was approximately $7,000. This policy is renewed annually at the end of the four year term with a nominal fee for the variance between the coverage requirement and the sinking fund balance. The Company has renewed this policy annually from 2011 to 2014 (with fees ranging from $41,000 to $46,000 annually). All other terms of the policy remain substantially unchanged.

	PROFIT SHARING PLAN
	We adopted a 401(k) Plan in 1992, which is intended to comply with Section 401 of the Internal Revenue Code and the provisions of the Employee Retirement Income Security Act of 1974. All full-time employees who have attained the age of 18 are eligible to participate in the 401(k) Plan. Eligibility is immediate upon employment but enrollment is only allowed during four quarterly open periods of January 1, April 1, July 1, and October 1. Participating employees may make annual pretax contributions to their accounts up to 100% of their compensation, up to a maximum amount as limited by law. The Company, at its discretion, may make matching contributions of 25% based on the employee’s elective contributions. Company contributions vest over a period of five years. Effective June 15, 2012, the Company suspended its matching contribution in an effort to reduce costs in light of the economic environment. The Company intends to contribute matching funds again effective January 1, 2015.

	BUSINESS ACQUISITION (SETTLEMENT AND RELEASE AGREEMENT)
	On February 12, 2013, the Company entered into a Settlement and Release Agreement (“Settlement Agreement”) with Timios National Corporation (“TNC” – formerly known as Homeland Security Capital Corporation) (the Company and TNC are collectively known as the “Parties”), in connection with the settlement of certain claims the Company made against TNC, subsequent to the acquisition of Safety and Ecology Holdings Corporation (“SEHC”) and its subsidiaries (collectively known as Safety and Ecology Corporation or “SEC”) on October 31, 2011 from TNC. The Settlement Agreement resolved (collectively, the “Subject Claims”): (a) the Disputed Claims, and (b) any other claim arising under the Stock Purchase Agreement, dated July 15, 2011 (“Purchase Agreement”) with respect to a breach of (i) the representations and warranties of the Parties contained in the Purchase Agreement, and (ii) certain covenants contained in the Purchase Agreement. Pursuant to the Settlement Agreement, the Parties agreed as follows:
		●	a promissory note issued to TNC (“October Note” - with original principal balance of $2,500,000 which was part consideration of the acquisition), with a principal balance of approximately $1,460,000 (at February 12, 2013), was cancelled, terminated and rendered null and void;
		●	the Company issued to TNC a new, two-year, non-negotiable, unsecured promissory note in the principal amount of approximately $230,000 (the “New Note”) in replacement of the October Note. The New Note bears an annual interest rate of 6%, payable in 24 monthly installments of principal and interest of approximately $10,000, with first payment due February 28, 2013;
		●	the remaining escrow balance of $500,000 was released to TNC. $2,000,000 was deposited into an escrow account as partial consideration of the purchase price and was established to satisfy any claims that we may have against TNC for indemnification pursuant to the Purchase Agreement. TNC and SEHC further agreed that if certain conditions were not met by December 31, 2011, relating to a certain contract, then the Company could withdraw $1,500,000 from the amount deposited into the escrow. On January 10, 2012, we received $1,500,000 from the escrow as certain conditions were not met under this certain contract as of December 31, 2011;
		●	the Parties terminated all of their rights and obligations to indemnification under the Purchase Agreement, except with respect to TNC’s covenants relating to non-compete, non-solicitation of customers and employees, confidentiality, and related remedies which will continue in full force and effect in accordance with the terms of the Purchase Agreement (the “Continuing Covenants”);
		●	the Parties terminated their rights and obligations with respect to (i) the representations, warranties, and covenants contained in the Purchase Agreement, except for the Continuing Covenants; and
		●	the Company terminated its contractual right to offset amounts owing to TNC under the Purchase Agreement to satisfy claims against TNC.
	In connection with the resolution of the Disputed Claims, we also entered into a Settlement and Release Agreement and Amendment to Employment Agreement (“Leichtweis Settlement”) with Christopher Leichtweis, our President of SEC, who voluntarily terminated and retired from all positions of the Company, effective May 24, 2013 (see discussion under Note 16 – “Related Party Transactions – Christopher Leichtweis” for a discussion of the Leichtweis Settlement and his voluntary termination and retirement).

	SEGMENT REPORTING
	In accordance with ASC 280, “Segment Reporting”, we define an operating segment as a business activity:
	●	from which we may earn revenue and incur expenses;
	●	whose operating results are regularly reviewed by the Chief Operating Officer (our Chief Operating Decision Maker) to make decisions about resources to be allocated to the segment and assess its performance; and
	●	for which discrete financial information is available.
	We currently have two reporting segments, Treatment and Services Segments, which are based on a service offering approach. This, however, excludes corporate headquarters, which do not generate revenue, our discontinued operations (see “Note 8 – Divestitures and Discontinued Operations”), and PF Medical S.A, a developmental entity whose primary purpose at this time is the R&D and marketing of medical isotope technology used in the medical diagnostic testing and is not generating any revenues (see Note 4 – “Perma-Fix Medical S.A.” for further information of this entity).

	SUBSEQUENT EVENTS
	Perma-Fix Medical S.A.
	During January 2015, Perma-Fix Medical, S.A. entered into a preliminary Letter of Intent (“LOI”) to form a strategic partnership and secure investment from a U.S company which is one of the largest national providers of in-office nuclear cardiology imaging services. This company uses Tc-99m in its nuclear imaging services business and provides imaging expertise to the medical community. Under the LOI, this company would, if the LOI is completed and definitive agreements are executed, invest $1,000,000 into Perma-Fix Medical S.A. The investment, when completed, would constitute approximately 5.4% of the outstanding common shares of Perma-Fix Medical S.A. When completed, this company will have the right to appoint one member to Perma-Fix Medical S.A.’s Supervisory Board, and a second appointee to either the Supervisory Board or the management team. The investment and agreements with this company are subject to numerous conditions, including, but not limited to, entering into definitive supply, stock purchase and other agreements, approval by each of the parties Boards and obtaining required approvals by Polish regulatory authorities as to issuance of the shares to this company.
	During January 2015, a consortium led by Perma-Fix Medical S.A. received an official notification from the National Centre for Research and Development in Poland for grant funding to further develop and commercialize a novel prototype generator for the production of Tc-99m for use in cancer and cardiac imaging (“Generator Project”). The total Generator Project budget is approximately $3,700,000, of which, Generator Project grant subsidies allocated to the project team will be approximately $2,800,000. Of the $2,800,000 grant allocation, Perma-Fix Medical S.A. will directly receive approximately $800,000 and the remaining amount will be allocated to other members of the Generator Project team to support technology development and testing. The Generator Project team will be under the leadership and supervision of Perma-Fix Medical S.A. and consists of four additional entities from Poland, including: the National Centre for Nuclear Research - Radioisotope Centre POLATOM in Otwock; the Institute for Biopolymers and Chemical Fibers - Department of Biopolymers in ŁódŹ; Warsaw Medical University - Department of Nuclear Administration; and the Institute of Industrial Organic Chemistry Branch in Pszczyna. The goal of the Generator Project is to develop a novel prototype generator utilizing Perma-Fix Medical S.A.’s microporous resin to produce molybdenum-derived Tc-99m, test the chemical and radionuclide purities of Tc-99m eluent and verify the performance of the final product, which will be the cancer and cardiac pharmaceutical kits used during animal and human imaging to fulfill both Polish and European Pharmacopoeia standards. The funding of this grant is subject to execution of agreements by Perma-Fix Medical S.A. with the project team partners and formal acceptance of the grant by Perma-Fix Medical S.A, which is expected to occur during the second quarter of 2015.

Accounting Policies [Abstract]
Consolidation, Policy [Policy Text Block]	Principles of Consolidation
	Our consolidated financial statements include our accounts and those of our wholly-owned subsidiaries after elimination of all significant intercompany accounts and transactions. The consolidated financial statements also include the accounts of SECRA, which we own 75%, and Perma-Fix Medical S.A., which we own 64%.

	Certain prior year amounts have been reclassified to conform with the current year presentation.
Use of Estimates, Policy [Policy Text Block]	Use of Estimates
	When the Company prepares financial statements in conformity with accounting standards generally accepted in the United States of America (“US GAAP”), the Company makes estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, as well as, the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. See Notes 8, 11, 12 and 13 for estimates of discontinued operations and environmental liabilities, closure costs, income taxes and contingencies for details on significant estimates.
Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy [Policy Text Block]	Restricted Cash
	Restricted cash reflects $35,000 held in escrow for our worker’s compensation policy and $50,000 held in escrow in connection with the divestiture of SYA on July 29, 2014 to be used to cover any potential claims made by the purchaser for indemnification for certain limited types of losses incurred by the purchaser within one year of the divestiture of SYA (see Note 8 – “Divestitures and Discontinued Operations” for further detail of this $50,000).
Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]	Accounts Receivable
	Accounts receivable are customer obligations due under normal trade terms requiring payment within 30 or 60 days from the invoice date based on the customer type (government, broker, or commercial). The carrying amount of accounts receivable is reduced by an allowance for doubtful accounts, which is a valuation allowance that reflects management's best estimate of the amounts that will not be collected. We regularly review all accounts receivable balances that exceed 60 days from the invoice date and based on an assessment of current credit worthiness, estimate the portion, if any, of the balance that will not be collected. This analysis excludes government related receivables due to our past successful experience in their collectability. Specific accounts that are deemed to be uncollectible are reserved at 100% of their outstanding balance. The remaining balances aged over 60 days have a percentage applied by aging category, based on historical experience that allows us to calculate the total allowance required. Once we have exhausted all options in the collection of a delinquent accounts receivable balance, which includes collection letters, demands for payment, collection agencies and attorneys, the account is deemed uncollectible and subsequently written off. The write off process involves approvals from senior management, based on, required approval thresholds.
	Retainage receivables represent amounts that are billed or billable to our customers, but are retained by the customer until completion of the project or as otherwise specified in the contract. Our retainage receivable balances are all current. Retainage receivables of approximately $11,000 and $135,000 as of December 31, 2014 and 2013, respectively, are included in the accounts receivable balance on the Company’s Consolidated Balance Sheets in the respective periods.
Trade and Other Accounts Receivable, Unbilled Receivables, Policy [Policy Text Block]	Unbilled Receivables
	Unbilled receivables are generated by differences between invoicing timing and our performance based methodology used for revenue recognition purposes. As major processing and contract completion phases are completed and the costs incurred, we recognize the corresponding percentage of revenue. Within our Treatment Segment, we experience delays in processing invoices due to the complexity of the documentation that is required for invoicing, as well as the difference between completion of revenue recognition milestones and agreed upon invoicing terms, which results in unbilled receivables. The timing differences occur for several reasons: partially from delays in the final processing of all wastes associated with certain work orders and partially from delays for analytical testing that is required after we have processed waste but prior to our release of waste for disposal. The tasks relating to these delays usually take several months to complete. As we now have historical data to review the timing of these delays, we realize that certain issues, including, but not limited to, delays at our third party disposal site, can extend collection of some of these receivables greater than twelve months. However, our historical experience suggests that a significant part of unbilled receivables are ultimately collectible with minimal concession on our part. We, therefore, segregate the unbilled receivables between current and long term.
	Unbilled receivables within our Services Segment can result from: (1) revenue recognized by our Earned Value Management program (a program which integrates project scope, schedule, and cost to provide an objective measure of project progress) but invoice milestones have not yet been met and/or (2) contract claims and pending change orders, including Requests for Equitable Adjustments (“REAs”) when work has been performed and collection of revenue is reasonably assured.
Inventory, Policy [Policy Text Block]	Inventories
	Inventories consist of treatment chemicals, saleable used oils, and certain supplies. Additionally, we have replacement parts in inventory, which are deemed critical to the operating equipment and may also have extended lead times should the part fail and need to be replaced. Inventories are valued at the lower of cost or market with cost determined by the first-in, first-out method.
Property, Plant and Equipment, Policy [Policy Text Block]	Property and Equipment
	Property and equipment expenditures are capitalized and depreciated using the straight-line method over the estimated useful lives of the assets for financial statement purposes, while accelerated depreciation methods are principally used for income tax purposes. Generally, asset lives range from ten to forty years for buildings (including improvements and asset retirement costs) and three to seven years for office furniture and equipment, vehicles, and decontamination and processing equipment. Leasehold improvements are capitalized and amortized over the lesser of the term of the lease or the life of the asset. Maintenance and repairs are charged directly to expense as incurred. The cost and accumulated depreciation of assets sold or retired are removed from the respective accounts, and any gain or loss from sale or retirement is recognized in the accompanying consolidated statements of operations. Renewals and improvements, which extend the useful lives of the assets, are capitalized.
	In accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 360, “Property, Plant, and Equipment”, long-lived assets, such as property, plant and equipment, and purchased intangible assets subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of are separately presented in the balance sheet and reported at the lower of the carrying amount or fair value less costs to sell, and are no longer depreciated. The assets and liabilities of a disposal group classified as held for sale would be presented separately in the appropriate asset and liability sections of the balance sheet.
	Our PFSG subsidiary is within our discontinued operations and is held for sale. On August 14, 2013, our PFSG facility incurred fire damage which has left it non-operational. The Company has recorded $723,000 and $130,000 in impairment charges for fixed assets related to the fire for the years ended December 31, 2014 and 2013, respectively.
	Our depreciation expense totaled approximately $3,602,000 and $3,381,000 in 2014 and 2013, respectively.
Goodwill and Intangible Assets, Policy [Policy Text Block]	Intangible Assets
	Intangible assets consist primarily of the recognized value of the permits required to operate our business and goodwill (as in previous years), or the cost of purchased businesses in excess of the estimated fair value of net identifiable assets acquired. As of December 31, 2014, we have no goodwill remaining. In connection with the sale of our SYA subsidiary on July 29, 2014, the Company recorded a goodwill impairment charge of $380,000 during the second quarter of 2014 for the SYA reporting unit. The Company fully impaired the goodwill for each of our Treatment, SEC, and CH Plateau Remediation Company (“CHPRC”) reporting units totaling approximately $27,856,000 during 2013. We continually reevaluate the propriety of the carrying amount of permits and goodwill (when applicable) to determine whether current events and circumstances warrant adjustments to the carrying value.
	Indefinite-lived intangible assets are not amortized but are reviewed for impairment annually as of October 1, or when events or changes in the business environment indicate that the carrying value may be impaired. If the fair value of the asset is less than the carrying amount, we perform a quantitative test to determine the fair value. The impairment loss, if any, is measured as the excess of the carrying value of the asset over its fair value. Significant judgments are inherent in these analyses and include assumptions for, among others factors, forecasted revenue, gross margin, growth rate, operating income, timing of expected future cash flows, and the determination of appropriate long term discount rates.
	We performed impairment testing of our permits related to our Treatment reporting unit as of October 1, 2014 and 2013 and determined no impairment existed.
	Intangible assets that have definite useful lives are amortized using the straight-line method over the estimated useful lives (with the exception of customer relationships which are amortized using an accelerated method) and are excluded from our annual intangible asset valuation review conducted as of October 1. The Company has one definite-lived permit which was excluded from our annual impairment review as noted above. The net carrying value of this one definite-lived permit as of December 31, 2014, was approximately $227,000. Definite-lived intangible assets are also tested for impairment whenever events or changes in circumstances suggest impairment might exist.
Goodwill	$0							$1,330,000	$29,186,000
Research and Development Expense, Policy [Policy Text Block]	Research and Development (“R&D”)
	Operational innovation and technical know-how is very important to the success of our business. Our goal is to discover, develop, and bring to market innovative ways to process waste that address unmet environmental needs and to develop new company service offerings. The Company conducts research internally and also through collaborations with other third parties. Research and development costs consist primarily of employee salaries and benefits, laboratory costs, third party fees, and other related costs associated with the development and enhancement of new potential waste treatment processes and are charged to expense when incurred in accordance with FASB ASC Topic 730, “Research and Development.” The Company’s R&D costs include R&D costs for our Perma-Fix Medical S.A., which primarily is to provide a financing vehicle for the development and marketing of its medical isotope (Tc-99m) technology used in medical diagnostic testing.
Asset Retirement Obligations, Policy [Policy Text Block]	Accrued Closure Costs and Asset Retirement Obligations (“ARO”)
	Accrued closure costs represent our estimated environmental liability to clean up our facilities as required by our permits, in the event of closure. ASC 410, “Asset Retirement and Environmental Obligations” requires that the discounted fair value of a liability for an ARO be recognized in the period in which it is incurred with the associated ARO capitalized as part of the carrying cost of the asset. The recognition of an ARO requires that management make numerous estimates, assumptions and judgments regarding such factors as estimated probabilities, timing of settlements, material and service costs, current technology, laws and regulations, and credit adjusted risk-free rate to be used. This estimate is inflated, using an inflation rate, to the expected time at which the closure will occur, and then discounted back, using a credit adjusted risk free rate, to the present value. ARO’s are included within buildings as part of property and equipment and are depreciated over the estimated useful life of the property. In periods subsequent to initial measurement of the ARO, the Company must recognize period-to-period changes in the liability resulting from the passage of time and revisions to either the timing or the amount of the original estimate of undiscounted cash flow. Increases in the ARO liability due to passage of time impact net income as accretion expense, which is included in cost of goods sold. Changes in costs resulting from changes or expansion at the facilities require adjustment to the ARO liability calculated and are capitalized and charged as depreciation expense, in accordance with the Company’s depreciation policy.
Income Tax, Policy [Policy Text Block]	Income Taxes
	Income taxes are accounted for in accordance with ASC 740, “Income Taxes.” Under ASC 740, the provision for income taxes is comprised of taxes that are currently payable and deferred taxes that relate to the temporary differences between financial reporting carrying values and tax bases of assets and liabilities. Deferred tax assets and liabilities are measured using enacted income tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Any effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.
	ASC 740 requires that deferred income tax assets be reduced by a valuation allowance if it is more likely than not that some portion or all of the deferred income tax assets will not be realized. The Company evaluates the realizability of its deferred income tax assets, primarily resulting from impairment loss and net operating loss carryforwards, and adjusts its valuation allowance, if necessary. Once the Company utilizes its net operating loss carryforwards or reverses the related valuation allowance it has recorded on these deferred tax assets, the Company would expect its provision for income tax expense in future periods to reflect an effective tax rate that will be significantly higher than past periods.
	ASC 740 sets out a consistent framework for preparers to use to determine the appropriate recognition and measurement of uncertain tax positions. ASC 740 uses a two-step approach wherein a tax benefit is recognized if a position is more-likely-than-not to be sustained. The amount of the benefit is then measured to be the highest tax benefit which is greater than 50% likely to be realized. ASC 740 also sets out disclosure requirements to enhance transparency of an entity’s tax reserves. The Company recognizes accrued interest and income tax penalties related to unrecognized tax benefits as a component of income tax expense.
	The Company reassesses the validity of our conclusions regarding uncertain income tax positions on a quarterly basis to determine if facts or circumstances have arisen that might cause us to change our judgment regarding the likelihood of a tax position’s sustainability under audit.
Foreign Currency Transactions and Translations Policy [Policy Text Block]	Foreign Currency
	The Company’s foreign subsidiaries include Perma-Fix Environmental Services UK Limited (“Perma-Fix UK Limited”), Perma-Fix Canada, Inc. and Perma-Fix Medical S.A. Assets and liabilities are translated to U.S. dollars at the exchange rate in effect at the balance sheet date and revenue and expenses at the average exchange rate for the period. Foreign currency translation adjustments for these subsidiaries are accumulated as a separate component of accumulated other comprehensive income (loss) in stockholders’ equity. Gains and losses resulting from foreign currency transactions are recognized in the consolidated statements of operations.
Concentration Risk, Credit Risk, Policy [Policy Text Block]	Concentration Risk
	The Company performed services relating to waste generated by the federal government, either directly as a prime contractor or indirectly as a subcontractor to the federal government, representing approximately $34,780,000 or 60.9% of total revenue from continuing operations during 2014, as compared to $47,557,000 or 63.9% of total revenue from continuing operations during 2013.
	The following customers accounted for 10% or more of the total revenues generated from continuing operations for twelve months ended December 31, 2014 and 2013:
			Total		% of Total
	Customer	Year	Revenue		Revenue
	United States Enrichment Corporation ("USEC")	2014	$	10,272,000		18	%
		2013	$	2,037,000		2.7	%
	CH Plateau Remediation Company ("CHPRC")	2014	$	5,762,000		10.1	%
		2013	$	19,922,000		26.8	%
	As revenues are event/project based where the completion of one contract with a specific customer may be replaced by another contract with a different customer from year to year, the Company does not believe the loss of one specific customer from one year to the next will generally have a material adverse effect on operations and financial condition.
	Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash and cash equivalents and accounts receivable. The Company maintains cash and cash equivalents with high quality financial institutions, which may exceed Federal Deposit Insurance Corporation (“FDIC”) insured amounts from time to time. Concentration of credit risk with respect to accounts receivable is limited due to the Company's large number of customers and their dispersion throughout the United States as well as with the significant amount of work that we perform for the federal government as discussed above.
	The Company has one customer whose net oustanding net receivable balance represented 13.4% and 13.9% of the Company’s total consolidated net accounts receivable at December 31, 2014 and 2013, respectively.
Gross Receipts Taxes And Other Charges [Policy Text Block]	Gross Receipts Taxes and Other Charges
	ASC 605-45, “Revenue Recognition – Principal Agent Consideration” provides guidance regarding the accounting and financial statement presentation for certain taxes assessed by a governmental authority. These taxes and surcharges include, among others, universal service fund charges, sales, use, waste, and some excise taxes. In determining whether to include such taxes in its revenue and expenses, the Company assesses, among other things, whether it is the primary obligor or principal taxpayer for the taxes assessed in each jurisdiction where the Company does business. As the Company is merely a collection agent for the government authority in certain of our facilities, the Company records the taxes on a net bases and excludes them from revenue and cost of services.
Revenue Recognition, Policy [Policy Text Block]	Revenue Recognition
	Treatment Segment revenues. The processing of mixed waste is complex and may take several months or more to complete; as such, the Treatment Segment recognizes revenues using a performance based methodology with its measure of progress towards completion determined based on output measures consisting of milestones achieved and completed. The Treatment Segment has waste tracking capabilities, which it continues to enhance, to allow for better matching of revenues earned to the processing phases achieved. The revenues are recognized as each of the following three processing phases are completed: receipt, treatment/processing and shipment/final disposal. However, based on the processing of certain waste streams, the treatment/processing and shipment/final disposal phases may be combined as sometimes they are completed concurrently. As major processing phases are completed and the costs incurred, the Treatment Segment recognizes the corresponding percentage of revenue utilizing a proportional performance model. The Treatment Segment experiences delays in processing invoices due to the complexity of the documentation that is required for invoicing, as well as the difference between completion of revenue recognition milestones and agreed upon invoicing terms, which results in unbilled receivables. The timing differences occur for several reasons, partially from delays in the final processing of all wastes associated with certain work orders and partially from delays for analytical testing that is required after the waste is processed waste but prior to our release of the waste for disposal. As the waste moves through these processing phases and revenues are recognized, the correlating costs are expensed as incurred. Although the Treatment Segment uses its best estimates and all available information to accurately determine these disposal expenses, the risk does exist that these estimates could prove to be inadequate in the event the waste requires retreatment. Furthermore, should the waste be returned to the customer, the related receivables could be uncollectible; however, historical experience has not indicated this to be a material uncertainty.
	Services Segment revenues. Revenue includes services performed under time and material, fixed price, and cost-reimbursement contracts. Revenues and costs associated with fixed price contracts are recognized using the percentage of completion (efforts expended) method. The Services Segment estimates its percentage of completion based on attainment of project milestones. Revenues and costs associated with time and material contracts are recognized as revenue when earned and costs are incurred.
	Under cost reimbursement contracts, the Services Segment is reimbursed for costs incurred plus a certain percentage markup for indirect costs, in accordance with contract provisions. Costs incurred in excess of contract funding may be renegotiated for reimbursement. The Services Segment also earns a fee based on the approved costs to complete the contract. The Services Segment recognizes this fee using the proportion of costs incurred to total estimated contract costs.
	Contract costs include all direct labor, material and other non-labor costs and those indirect costs related to contract support, such as depreciation, fringe benefits, overhead labor, supplies, tools, repairs and equipment rental. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined. Changes in job performance, job conditions and estimated profitability, including those arising from contract penalty provisions and final contract settlements, may result in revisions to costs and income and are recognized in the period in which the revisions are determined.
Self Insurance [Policy Text Block]	Self-Insurance
	The Company is self-insured for a significant portion of our group health. The Company estimates expected losses based on statistical analyses of historical industry data, as well as our own estimates based on the Company’s actual historical data to determine required self-insurance reserves. The assumptions are closely reviewed, monitored, and adjusted when warranted by changing circumstances. The estimated accruals for these liabilities could be affected if actual experience related to the number of claims and cost per claim differs from these assumptions and historical trends. Based on the information known on December 31, 2014, the Company believes it has provided adequate reserves for our self-insurance exposure. As of December 31, 2014 and 2013, self-insurance reserves were $397,000 and $473,000, respectively, and were included in Accrued expenses in the accompanying consolidated balance sheets. The total amounts expensed for self-insurance during 2014 and 2013 were $2,697,000, and $2,906,000, respectively, for our continuing operations.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Stock-Based Compensation
	The Company accounts for stock-based compensation in accordance with ASC 718, “Compensation – Stock Compensation”. ASC 718 requires all stock-based payments to employees, including grants of employee stock options, to be recognized in the income statement based on their fair values. The Company uses the Black-Scholes option-pricing model to determine the fair-value of stock-based awards which requires subjective assumptions. Assumptions used to estimate the fair value of stock options granted include the exercise price of the award, the expected term, the expected volatility of the Company’s stock over the option’s expected term, the risk-free interest rate over the option’s expected term, and the expected annual dividend yield.
	The Company recognizes stock-based compensation expense using a straight-line amortization method over the requisite service period, which is the vesting period of the stock option grant. As ASC 718 requires that stock-based compensation expense be based on options that are ultimately expected to vest, our stock-based compensation expense is reduced by an estimated forfeiture rate. Our estimated forfeiture rate is generally based on historical trends of actual forfeitures. Forfeiture rates are evaluated, and revised as necessary.
Comprehensive Income, Policy [Policy Text Block]	Comprehensive Income
	The components of comprehensive income are net income and the effects of foreign currency translation adjustments.
Earnings Per Share, Policy [Policy Text Block]	Earnings Per Share
	Basic earnings per share is calculated based on the weighted-average number of outstanding common shares during the applicable period. Diluted earnings per share is based on the weighted-average number of outstanding common shares plus the weighted-average number of potential outstanding common shares. Earnings per share is computed separately for each period presented.
	The diluted loss per share calculations exclude options to purchase approximately 201,000 and 339,000 shares of common stock for the years ended December 31, 2014 and 2013, respectively, because their effect would have been antidilutive as a result of the net losses recorded in these periods.
Fair Value Measurement, Policy [Policy Text Block]	Fair Value of Financial Instruments
	Certain assets and liabilities are required to be recorded at fair value on a recurring basis, while other assets and liabilities are recorded at fair value on a nonrecurring basis.  Fair value is determined based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. The three-tier value hierarchy, which prioritizes the inputs used in the valuation methodologies, is:
	Level 1—Valuations based on quoted prices for identical assets and liabilities in active markets.
	Level 2—Valuations based on observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data.
	Level 3—Valuations based on unobservable inputs reflecting the Company’s own assumptions, consistent with reasonably available assumptions made by other market participants.
	Financial instruments include cash and restricted cash (Level 1), accounts receivable, accounts payable, and debt obligations (Level 3).  Credit is extended to customers based on an evaluation of a customer’s financial condition and, generally, collateral is not required. At December 31, 2014 and December 31, 2013, the fair value of the Company’s financial instruments approximated their carrying values.  The fair value of the Company’s revolving credit facility approximates its carrying value due to the variable interest rate. The carrying value of our subsidiary's preferred stock is not significantly different than its fair value.
New Accounting Pronouncements, Policy [Policy Text Block]	Recently Adopted Accounting Standards
	In April 2014, the FASB issued Accounting Standards Update (“ASU”) No. 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity.” ASU 2014-08, among other things, raises the threshold for disposals to qualify as discontinued operations. Under ASU 2014-08, a discontinued operation is (1) a component of an entity or group of components that has been disposed of by sale, disposed of other than by sale or is classified as held for sale that represents a strategic shift that has or will have a major effect on an entity’s operations and financial results or (2) an acquired business or nonprofit activity that is classified as held for sale on the date of the acquisition. ASU 2014-08 also requires additional disclosures for discontinued operations and new disclosures for individually material disposal transactions that do not meet the definition of a discontinued operation. This ASU is effective for annual periods beginning on or after December 15, 2014 and interim periods within that year. Early adoption of ASU 2014-08 was permitted but only for disposals (or classifications as held for sale) that were not reported in financial statements previously issued or available for issue. The Company early adopted ASU 2014-08 during the second quarter of 2014. On April 3, 2014, the Company’s Board of Directors (“Board”) approved management to pursue the sale of our wholly owned subsidiary, SYA. On July 29, 2014, the Company completed the divestiture of SYA. In accordance with ASU 2014-08, the divestiture of SYA is presented within our continuing operations. The sale of SYA did not represent a strategic shift that has had a major effect on the Company's operations and financial results as defined by ASU 2014-08.
	In November 2014, the FASB issued ASU 2014-17, “Pushdown Accounting”. ASU 2014-17 provides companies with the option to apply pushdown accounting in its separate financial statements upon occurrence of an event in which an acquirer obtains control of the acquired entity. The election to apply pushdown accounting can be made either in the period in which the change of control occurred, or in a subsequent period. This ASU is effective as of November 18, 2014. The adoption of this ASU did not have an impact on the Company's results of operations, cash flows or financial position
New Accounting Pronouncements Not Yet Adopted [Policy Text Block]	Recently Issued Accounting Standards – Not Yet Adopted
	In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606).” ASU 2014-09 provides a single, comprehensive revenue recognition model for all contracts with customers. The revenue guidance contains principles that an entity will apply to determine the measurement of revenue and timing of when it is recognized. The underlying principle is that an entity will recognize revenue to depict the transfer of goods or services to customers at an amount that the entity expects to be entitled to in exchange for those goods or services. The standard will be effective for the first interim period within annual reporting periods beginning after December 15, 2016 for public entities, with no early adoption permitted, and allows for either full retrospective adoption or modified retrospective adoption. The Company is still evaluating the potential impact of adopting this guidance on our financial statements.
	In June 2014, the FASB issued ASU 2014-12, “Compensation Stock – Compensation (Topic 718).” ASU 2014-12 applies to all reporting entities that grant their employees share-based payments in which the terms of the award provide that a performance target that affects vesting could be achieved after the requisite service period. It requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition and follows existing accounting guidance for the treatment of performance conditions. The standard is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015, with early adoption permitted. The Company is still evaluating the potential impact of adopting this guidance on our financial statements.
	In August 2014, the FASB issued ASU No. 2014-15, “Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern.” ASU 2014-15 requires management to assess an entity’s ability to continue as a going concern, and to provide related footnote disclosure in certain circumstances. The new standard will be effective for all entities in the first annual period ending after December 15, 2016. The Company is still evaluating the potential impact of adopting this guidance on our financial statements.
	In November 2014, the FASB issued ASU, 2014-16, “Determining Whether the Host Contract in a Hybrid Financial Instrument Issued in the Form of a Share Is More Akin to Debt or to Equity.” ASU 2014-06 clarifies how current guidance should be interpreted in evaluating the economic characteristics and risks of a host contract in a hybrid financial instrument that is issued in the form of a share. Specifically, the amendments clarify that an entity should consider all relevant terms and features, including the embedded derivative feature being evaluated for bifurcation, in evaluating the nature of a host contract. The ASU is effective for fiscal years and interim periods beginning after December 15, 2015.
