Accounting Policies [Abstract]
Basis of Presentation	1. Basis of Presentation The consolidated 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 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 six months ended June 30, 2022 are not necessarily indicative of results to be expected for the fiscal year ending December 31, 2022. The Company suggests that these consolidated 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, 2021. The consolidated financial statements include the accounts of our wholly-owned subsidiaries and the account of a variable interest entity (“VIE”), Perma-Fix ERRG, for which we are the primary beneficiary (See “Note 14 - VIE” for a discussion of this VIE). The consolidated financial statements for 2021 also included the accounts of the Company’s majority-owned Polish subsidiary, Perma-Fix Medical S.A (“PFM Poland”) and PFM Poland’s wholly-owned subsidiary, Perma-Fix Medical Corporation (“PFMC”), which comprised of the Company’s Medical Segment. As previously discussed, the Company made the strategic decision to cease all research and development (“R&D”) activities under the Medical Segment and sold 100 Information for the Medical Segment is presented for the quarter and six months ended June 30, 2021. The Medical Segment was disposed of as of December 31, 2021 and is not relevant for the quarter and six month ended June 30, 2022. Prior period segment information is not required to be restated for the disposal of the segment.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Our accounting policies are as set forth in the notes to the December 31, 2021 consolidated financial statements referred to above. Recently Adopted Accounting Standards In May 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2021-04, “Earnings Per Share (Topic 206), Debt-Modifications and Extinguishments (Subtopic 470-50), Compensation-Stock Compensation (Topic 718), and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40): Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options (a consensus of the FASB Emerging Issues Task Force).” ASU 2021-04 addresses issuer’s accounting for certain modifications or exchanges of freestanding equity-classified written call options. This ASU is effective for all entities, for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. Early adoption is permitted. The adoption of this ASU by the Company effective January 1, 2022 did not have a material impact on its financial statements. Recently Issued Accounting Standards – Not Yet Adopted In June 2016, the FASB issued ASU No. 2016-13, “Credit Losses (Topic 326) - Measurement of Credit Losses on Financial Instruments,” and various subsequent amendments to the initial guidance (collectively, “Topic 326”). Topic 326 introduces an approach, based on expected losses, to estimate credit losses on certain types of financial instruments and modifies the impairment model for available-for-sale debt securities. The new approach to estimating credit losses (referred to as the current expected credit losses model) applies to most financial assets measured at amortized cost and certain other instruments, including trade and other receivables and loans. Entities are required to apply the standard’s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. In November 2019, FASB issued ASU 2019-10, “Financial Instruments – Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842),” which defers the effective date of ASU 2016-13 for public companies that are considered smaller reporting companies (“SRC”) as defined by the Commission to fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. These ASUs are effective January 1, 2023 for the Company as an SRC. Under new guidance issued by the Commission in March 2020, the Company continued to qualify as a SRC but became an accelerated filer for its 2021 Form 10-K and its 2022 quarterly 10-Q filings. The Company will remain a SRC but will become a non-accelerated filer for its 2022 Form 10-K and subsequent filings. The Company is currently evaluating the impact of these ASU on its consolidated financial statements. In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting,” which provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships and other transactions affected by the discontinuation of the London Interbank Offered Rate (“LIBOR”) or by another reference rate expected to be discontinued because of reference rate reform. The guidance was effective beginning March 12, 2020 and can be applied prospectively through December 31, 2022. In January 2021, the FASB issued ASU No. 2021-01, “Reference Rate Reform (Topic 848): Scope,” which clarified the scope and application of the original guidance. The Company plans to adopt both ASUs when LIBOR is discontinued. The Company is currently evaluating the impact of the new ASUs on its condensed consolidated financial statements. As of the date of this report, the Company has determined that only its obligations under the credit facility as described in “Note 8 – Long Term Debt” would be impacted by these ASUs. The Company’s obligations under its credit facility permit for payment of annual rate of interests on its obligations using prime rate or LIBOR. In August 2020, the FASB issued ASU No. 2020-06, “Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity.” ASU 2020-06 simplifies the accounting for convertible instruments by removing major separation models and removing certain settlement condition qualifiers for the derivatives scope exception for contracts in an entity’s own equity, and simplifies the related diluted net income per share calculation for both Subtopics. ASU 2020-06 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2023, for the Company as an SRC. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The Company is currently evaluating the impact of this ASU on its consolidated financial statements and disclosures.

Variable Interest Entities (“VIE”)	14. Variable Interest Entities (“VIE”) The Company and Engineering/Remediation Resources Group, Inc. (“ERRG”) previously entered into an unpopulated joint venture agreement for project work bids within the Company’s Services Segment with the joint venture doing business as Perma-Fix ERRG, a general partnership. The Company has a 51 49 The Company determines whether joint ventures in which it has invested meet the criteria of a VIE at the start of each new venture and when a reconsideration event has occurred. A VIE is a legal entity that satisfies any of the following characteristics: (a) the legal entity does not have sufficient equity investment at risk; (b) the equity investors at risk as a group, lack the characteristics of a controlling financial interest; or (c) the legal entity is structured with disproportionate voting rights. The Company consolidates a VIE if it is determined to be the primary beneficiary of the VIE. The primary beneficiary has both the power to direct the activities of the VIE that most significantly impact the entity’s economic performance and the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE. Based on the Company’s evaluation of Perma-Fix ERRG and related agreements with Perma-Fix ERRG, the Company determined that Perma-Fix ERRG continues to be a VIE in which we are the primary beneficiary. At June 30, 2022, Perma-Fix ERRG had total assets of $ 105,000 and total liabilities of approximately $ 105,000 which are all recorded as current.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	6 Months Ended
	Jun. 30, 2022
Accounting Policies [Abstract]
Recently Adopted Accounting Standards	Recently Adopted Accounting Standards In May 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2021-04, “Earnings Per Share (Topic 206), Debt-Modifications and Extinguishments (Subtopic 470-50), Compensation-Stock Compensation (Topic 718), and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40): Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options (a consensus of the FASB Emerging Issues Task Force).” ASU 2021-04 addresses issuer’s accounting for certain modifications or exchanges of freestanding equity-classified written call options. This ASU is effective for all entities, for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. Early adoption is permitted. The adoption of this ASU by the Company effective January 1, 2022 did not have a material impact on its financial statements.
Recently Issued Accounting Standards – Not Yet Adopted	Recently Issued Accounting Standards – Not Yet Adopted In June 2016, the FASB issued ASU No. 2016-13, “Credit Losses (Topic 326) - Measurement of Credit Losses on Financial Instruments,” and various subsequent amendments to the initial guidance (collectively, “Topic 326”). Topic 326 introduces an approach, based on expected losses, to estimate credit losses on certain types of financial instruments and modifies the impairment model for available-for-sale debt securities. The new approach to estimating credit losses (referred to as the current expected credit losses model) applies to most financial assets measured at amortized cost and certain other instruments, including trade and other receivables and loans. Entities are required to apply the standard’s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. In November 2019, FASB issued ASU 2019-10, “Financial Instruments – Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842),” which defers the effective date of ASU 2016-13 for public companies that are considered smaller reporting companies (“SRC”) as defined by the Commission to fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. These ASUs are effective January 1, 2023 for the Company as an SRC. Under new guidance issued by the Commission in March 2020, the Company continued to qualify as a SRC but became an accelerated filer for its 2021 Form 10-K and its 2022 quarterly 10-Q filings. The Company will remain a SRC but will become a non-accelerated filer for its 2022 Form 10-K and subsequent filings. The Company is currently evaluating the impact of these ASU on its consolidated financial statements. In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting,” which provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships and other transactions affected by the discontinuation of the London Interbank Offered Rate (“LIBOR”) or by another reference rate expected to be discontinued because of reference rate reform. The guidance was effective beginning March 12, 2020 and can be applied prospectively through December 31, 2022. In January 2021, the FASB issued ASU No. 2021-01, “Reference Rate Reform (Topic 848): Scope,” which clarified the scope and application of the original guidance. The Company plans to adopt both ASUs when LIBOR is discontinued. The Company is currently evaluating the impact of the new ASUs on its condensed consolidated financial statements. As of the date of this report, the Company has determined that only its obligations under the credit facility as described in “Note 8 – Long Term Debt” would be impacted by these ASUs. The Company’s obligations under its credit facility permit for payment of annual rate of interests on its obligations using prime rate or LIBOR. In August 2020, the FASB issued ASU No. 2020-06, “Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity.” ASU 2020-06 simplifies the accounting for convertible instruments by removing major separation models and removing certain settlement condition qualifiers for the derivatives scope exception for contracts in an entity’s own equity, and simplifies the related diluted net income per share calculation for both Subtopics. ASU 2020-06 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2023, for the Company as an SRC. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The Company is currently evaluating the impact of this ASU on its consolidated financial statements and disclosures.
