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 nine months ended September 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.

Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Our accounting policies are set forth in the notes to the December 31, 2022 consolidated financial statements referred to above. Recently Issued Accounting Standards – Not Yet Adopted In August 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-05, “Business Combinations—Joint Venture Formations (Subtopic 805-60): Recognition and Initial Measurement.” ASU 2023-05 applies to the formation of a “joint venture” or a “corporate joint venture” and requires a joint venture to initially measure all contributions received upon its formation at fair value. The guidance does not impact accounting by the venturers. The new guidance is applicable to joint venture entities with a formation date on or after January 1, 2025 on a prospective basis. ASU 2023-05 is currently not applicable to the Company; however, the Company will apply this guidance in future reporting periods after the guidance is effective to any future arrangements meeting this standard.
