Accounting Policies [Abstract]
Basis of Presentation	1. Basis of Presentation The condensed 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 condensed 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, 2023, are not necessarily indicative of results to be expected for the fiscal year ending December 31, 2023. The Company suggests that these condensed 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, 2022. The condensed consolidated financial statements include the accounts of our wholly-owned subsidiaries. The Company’s continuing operations also consisted of Perma-Fix ERRG, a variable interest entity (“VIE”) for which we were the primary beneficiary. During the fourth quarter of 2022, project work under the joint venture was completed.

Within our Services Segment, there are service contracts which provide that the Company has a right to consideration from a customer in an amount that corresponds directly with the value to the customer of our performance completed to date. For those contracts, the Company has utilized the practical expedient in ASC 606-10-55-18, which allows the Company to recognize revenue in the amount for which we have the right to invoice; accordingly, the Company does not disclose the value of remaining performance obligations for those contracts. The Company’s contracts and subcontracts relating to activities at governmental sites generally allow for termination for convenience at any time at the government’s option without payment of a substantial penalty. The Company does not disclose remaining performance obligations on these contracts.

Following these amendments, the Company determined that it was eligible for the ERC, and as a result of the foregoing legislations, was eligible to claim a refundable tax credit against the Company’s share of certain payroll taxes equal to 70 10,000 7,000 During the third quarter of 2022, the Company determined it was eligible for the ERC and amended its third quarter 2021 employer payroll tax filings claiming a refund from the U.S. Treasury in the amount of approximately $ 1,975,000 1,975,000 60,000 2,035,000
