Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	1. Basis of Presentation The consolidated condensed financial statements included herein have been prepared by the Company (which may be referred to as we, us or our), without an audit, pursuant to the rules and regulations of the Securities and Exchange Commission (“the Commission”). Certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) have been condensed or omitted pursuant to such rules and regulations, although the Company believes the disclosures which are made are adequate to make the information presented not misleading. Further, the consolidated condensed financial statements reflect, in the opinion of management, all adjustments (which include only normal recurring adjustments) necessary to present fairly the financial position and results of operations as of and for the periods indicated. The results of operations for the three months ended March 31, 2016 are not necessarily indicative of results to be expected for the fiscal year ending December 31, 2016. The Company suggests that these consolidated condensed financial statements be read in conjunction with the consolidated financial statements and the notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2015. As disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015, the Company determined that the operations of its majority-owned subsidiary, Perma-Fix Medical S.A. (“PF Medical”), which has not generated any revenues as it continues to be primarily in the research and development (“R&D”) stage, meet the definition of a reportable segment in accordance with Accounting Standards Codification (“ASC”) 280, “Segment Reporting.” Accordingly, as detailed on Note 9 – “Operation Segments,” all of the historical numbers presented in the consolidated financial statements have been recast to include the operations of PF Medical as a separate reportable segment (“Medical Segment”). Reclassification Certain prior year amounts have been reclassified to conform with the current year presentation.

Notes to Financial Statements
Significant Accounting Policies [Text Block]	2. Summary of Significant Accounting Policies Our accounting policies are as set forth in the notes to the December 31, 2015 consolidated financial statements referred to above. During the first quarter of 2016, all of the restricted cash previously held in escrow at December 31, 2015 was released. Such amount represented $35,000 held in escrow for our worker’s compensation policy with the remaining representing proceeds held in escrow resulting from stock subscription agreements executed in connection with the sale of common stock by PF Medical in previous years. Recently Adopted Accounting Standards In April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-03, "Simplifying the Presentation of Debt Issuance Costs." ASU 2015-03 amends existing guidance to require the presentation of debt issuance costs in the balance sheet as a deduction from the carrying amount of the related debt liability instead of a deferred charge asset. It is effective for annual reporting periods beginning after December 15, 2015 (including interim reporting periods), but early adoption is permitted. The Company adopted ASU 2015-03 retroactively in the first quarter of 2016. The adoption of ASU 2015-03 did not have a material impact to the Company’s results of operations, cash flows or financial position . The adoption of ASU 2015-03 resulted in a decrease in prepaid and other assets of approximately $152,000, a decrease in current portion of long-term debt of $27,000, and a decrease in long-term debt, less current portion of $125,000 for the balances as of December 31, 2015 in the accompanying Consolidated Balance Sheets. 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. In July 2015, the FASB deferred the effective date to annual reporting periods beginning after December 15, 2017 (including interim reporting periods within those periods). Early adoption is permitted to the original effective date of periods beginning after December 15, 2016 (including interim reporting periods within those periods). The ASU may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of initial application. 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 July 2015, the FASB issued ASU 2015-11, “Inventory (Topic 330): Simplifying the Measurement of Inventory.” ASU In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)”. Under ASU 2016-02, an entity will be required to recognize right-of-use assets and lease liabilities on its balance sheet and disclose key information about leasing arrangements. ASU 2016-02 offers specific accounting guidance for a lessee, a lessor and sale and leaseback transactions. Lessees and lessors are required to disclose qualitative and quantitative information about leasing arrangements to enable a user of the financial statements to assess the amount, timing and uncertainty of cash flows arising from leases. For public companies, ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period, and requires a modified retrospective adoption, with early adoption permitted. The Company is still evaluating the potential impact of adopting this guidance on our financial statements. In March 2016, the FASB issued ASU 2016-07, “Investments- Equity Method and Joint Ventures: Simplifying the Transition to the Equity Method of Accounting.” ASU 2016-07 eliminates the requirement to apply the equity method of accounting retrospectively when a reporting entity obtains significant influence over a previously held investment. ASU 2016-07 is effective for interim and annual periods beginning after December 15, 2016. The Company is still evaluating the potential impact of adopting this guidance on our financial statements. In March 2016, the FASB issued ASU 2016-08, “Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net).” ASU 2016-08 does not change the core principle of the guidance stated in ASU 2014-09; instead, the amendments in this ASU are intended to improve the operability and understandability of the implementation guidance on principal versus agent considerations and whether an entity reports revenue on a gross or net basis. ASU 2016-08 will have the same effective date and transition requirements as the new revenue standard issued in ASU 2014-09. The Company is still evaluating the potential impact of adopting this guidance on our financial statements. In March 2016, the FASB issued ASU 2016-09, “Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” ASU 2016-09 simplifies several aspects related to the accounting for share-based payment transactions, including the accounting for income taxes, statutory tax withholding requirements and classification on the statement of cash flows. ASU 2016-07 is effective for interim and annual periods beginning after December 15, 2016. The Company is still evaluating the potential impact of adopting this guidance on our financial statements.

Earnings Per Share [Text Block]	5. Loss Per Share Basic loss per share is calculated based on the weighted-average number of outstanding common shares during the applicable period. Diluted loss per share is based on the weighted-average number of outstanding common shares plus the weighted-average number of potential outstanding common shares. In periods where they are anti-dilutive, such amounts are excluded from the calculations of dilutive earnings per shares.

The Loan Agreement, as subsequently amended (“Amended Loan Agreement”), provided the Company with the following Credit Facility: (a) up to $12,000,000 revolving credit (“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 required monthly installments of approximately $190,000 (based on a seven-year amortization). Under the Amended Loan Agreement, the Company had the option of paying an annual rate of interest due on the Revolving Credit at prime plus 2% or London Inter Bank Offer Rate (“LIBOR”) plus 3% and the Term Loan at prime plus 2.5% or LIBOR plus 3.5%. On March 24, 2016, the Company entered into an amendment to the Amended Loan Agreement with PNC which provided, among other things, the following (the amendment, together with the Amended Loan Agreement is collectively known as the “Revised Loan Agreement”): ● extended the due date of our Credit Facility from October 31, 2016 to March 24, 2021 (“maturity date”); ● amended the Term loan to approximately $6,100,000, which requires monthly payments of $101,600 (based on a five-year amortization) and which approximated the term loan balance under the existing Credit Facility at the date of the amendment. The revolving line of credit remains at up to $12,000,000 (subject to the amount of borrowings based on a percentage of eligible receivables as previously defined under the Amended Loan Agreement); ● released $1,000,000 of the $1,500,000 borrowing availability restriction that the lender had previously placed on the Company in connection with the insurance settlement proceeds received on July 28, 2014 by our PFSG facility, which suffered a fire in 2013. The Company’s lender had authorized the Company to use such proceeds for working capital purposes but had placed an indefinite reduction on our borrowing availability of $1,500,000; ● revised the interest payment options to paying an annual rate of interest due on the Revolving Credit at prime plus 1.75% or LIBOR plus 2.75% and the Term Loan at prime plus 2.25% or LIBOR plus 3.25%; and ● revised our annual capital spending maximum limit from $6,000,000 to $3,000,000. In connection with the amendment, the Company paid PNC a closing fee of $70,000. As a result of the amendment dated March 24, 2016, the Company recorded approximately $68,000 in loss on extinguishment of debt in accordance with ASC 470-50, “Debt – Modifications and Extinguishments,” which has been included in interest expense in the accompanying Consolidated Statements of Operations. Pursuant to the amendment, the Company may terminate the Revised Loan Agreement upon 90 days’ prior written notice upon payment in full of its obligations under the Revised Loan Agreement. The Company has agreed to pay PNC 1.0% of the total financing in the event the Company pays off its obligations on or before March 23, 2017, .50% of the total financing if the Company pays off its obligations after March 23, 2017 but prior to or on March 23, 2018, and .25% of the total financing if the Company pays off its obligations after March 23, 2018 but prior to or on March 23, 2019. No early termination fee shall apply if the Company pays off its obligations after March 23, 2019. All other terms of the Amended Loan Agreement remain principally unchanged. As of March 31, 2016, the availability under our revolving credit was $2,740,000, based on our eligible receivables and includes the remaining indefinite reduction of borrowing availability of $500,000 as discussed above. The Company’s 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. The Company met its quarterly financial covenants in the first quarter of 2016 with the exception of its minimum quarterly fixed charge coverage ratio requirement of 1.15:1. The Company has obtained a waiver from its lender for this non-compliance (see Note 11- “Subsequent Events – Credit Facility”). The Company expects to meet its quarterly financial covenants in each of the remaining quarters of 2016. Promissory Note The Company entered into a $3,000,000 loan dated August 2, 2013 with Messrs. Robert Ferguson and William Lampson (each known as the “Lender”). As consideration for the Company receiving the loan, the Company issued to each Lender a Warrant to purchase up to 35,000 shares of the Company’s Common at an exercise price of $2.23 per share. The Warrants expire on August 2, 2016. As further consideration for the loan, the Company also issued to each Lender 45,000 shares of the Company’s Common Stock. The fair value of the Warrants and Common Stock and the related closing fees incurred from this 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.

Commitments and Contingencies Disclosure [Text Block]	7. Commitments and Contingencies Hazardous Waste In connection with our waste management services, we process 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, have been made by the Company. As of March 31, 2016, our financial assurance coverage amount under this policy totaled approximately $38,874,000. The Company has recorded $15,474,000 in sinking fund related to this policy in other long term assets on the accompanying Consolidated Balance Sheets, which includes interest earned of $1,003,000 on the sinking fund as of March 31, 2016. Interest income for the three months ended March 31, 2016 and 2015 was approximately $14,000 and $6,000, respectively. If the Company so elects, AIG is obligated to pay the Company 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 March 31, 2016, the Company has recorded $5,922,000 in our sinking fund related to this policy in other long term assets on the accompanying Consolidated Balance Sheets, which includes interest earned of $222,000 on the sinking fund as of March 31, 2016. Interest income for the three months ended March 31, 2016 and 2015 was approximately $2,000 and $1,000, respectively. 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 2015 (with fees ranging from $41,000 to $46,000 annually). All other terms of the policy remain substantially unchanged. Letter s of Credit and Bonding Requirements From time to time, we are required to post standby letters of credit and various bonds to support contractual obligations to customers and other obligations, including facility closures. As of March 31, 2016, the total amount of these bonds and letters of credit outstanding was approximately $1,539,000, of which the majority of the amount relates to various bonding requirements.

Significant Accounting Policies

Significant Accounting Policies (Policies)	3 Months Ended

Accounting Policies [Abstract]
New Accounting Pronouncements, Policy [Policy Text Block]	Recently Adopted Accounting Standards In April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-03, "Simplifying the Presentation of Debt Issuance Costs." ASU 2015-03 amends existing guidance to require the presentation of debt issuance costs in the balance sheet as a deduction from the carrying amount of the related debt liability instead of a deferred charge asset. It is effective for annual reporting periods beginning after December 15, 2015 (including interim reporting periods), but early adoption is permitted. The Company adopted ASU 2015-03 retroactively in the first quarter of 2016. The adoption of ASU 2015-03 did not have a material impact to the Company’s results of operations, cash flows or financial position . The adoption of ASU 2015-03 resulted in a decrease in prepaid and other assets of approximately $152,000, a decrease in current portion of long-term debt of $27,000, and a decrease in long-term debt, less current portion of $125,000 for the balances as of December 31, 2015 in the accompanying Consolidated Balance Sheets.
New Accounting Pronouncements not yet Adopted, Policy [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. In July 2015, the FASB deferred the effective date to annual reporting periods beginning after December 15, 2017 (including interim reporting periods within those periods). Early adoption is permitted to the original effective date of periods beginning after December 15, 2016 (including interim reporting periods within those periods). The ASU may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of initial application. 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 July 2015, the FASB issued ASU 2015-11, “Inventory (Topic 330): Simplifying the Measurement of Inventory.” ASU In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)”. Under ASU 2016-02, an entity will be required to recognize right-of-use assets and lease liabilities on its balance sheet and disclose key information about leasing arrangements. ASU 2016-02 offers specific accounting guidance for a lessee, a lessor and sale and leaseback transactions. Lessees and lessors are required to disclose qualitative and quantitative information about leasing arrangements to enable a user of the financial statements to assess the amount, timing and uncertainty of cash flows arising from leases. For public companies, ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period, and requires a modified retrospective adoption, with early adoption permitted. The Company is still evaluating the potential impact of adopting this guidance on our financial statements. In March 2016, the FASB issued ASU 2016-07, “Investments- Equity Method and Joint Ventures: Simplifying the Transition to the Equity Method of Accounting.” ASU 2016-07 eliminates the requirement to apply the equity method of accounting retrospectively when a reporting entity obtains significant influence over a previously held investment. ASU 2016-07 is effective for interim and annual periods beginning after December 15, 2016. The Company is still evaluating the potential impact of adopting this guidance on our financial statements. In March 2016, the FASB issued ASU 2016-08, “Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net).” ASU 2016-08 does not change the core principle of the guidance stated in ASU 2014-09; instead, the amendments in this ASU are intended to improve the operability and understandability of the implementation guidance on principal versus agent considerations and whether an entity reports revenue on a gross or net basis. ASU 2016-08 will have the same effective date and transition requirements as the new revenue standard issued in ASU 2014-09. The Company is still evaluating the potential impact of adopting this guidance on our financial statements. In March 2016, the FASB issued ASU 2016-09, “Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” ASU 2016-09 simplifies several aspects related to the accounting for share-based payment transactions, including the accounting for income taxes, statutory tax withholding requirements and classification on the statement of cash flows. ASU 2016-07 is effective for interim and annual periods beginning after December 15, 2016. The Company is still evaluating the potential impact of adopting this guidance on our financial statements.
