Massachusetts Man Pleads Guilty to Illegally Selling Russian Radioactive Material

The case tests the reach of federal statutes governing radioactive material imports and raises questions about supply chain oversight for controlled substances originating from sanctioned nations.

A Massachusetts man pleaded guilty to federal charges related to the illegal importation and sale of radioactive material sourced from Russia, the U.S. Department of Justice announced Monday, October 6, 2026, according to NBC News.

Federal prosecutors stated the defendant imported the radioactive material from Russia and subsequently sold it within the United States. The precise isotope or isotopes involved, the quantities sold, and the identities of buyers have not been disclosed in publicly available court filings reviewed as of publication. The case number and the specific federal district court in which the plea was entered were not identified in the initial prosecutor announcement.

The charges fall under federal statutes governing the importation and distribution of radioactive materials. Under 18 U.S.C. Section 831, which addresses nuclear materials offenses, and regulations administered by the Nuclear Regulatory Commission (NRC), individuals are prohibited from importing, possessing, or transferring certain radioactive materials without federal licensing. Whether the defendant held any NRC license at any point is not stated in currently available public records.

The case carries significance for U.S. National security and public health regulatory frameworks. Russia has been subject to broad U.S. Economic sanctions since 2022, administered by the Office of Foreign Assets Control (OFAC) at the U.S. Department of the Treasury. Whether the defendant faced additional OFAC-related charges related to those sanctions is not confirmed in available court records.

The NRC maintains a public database of licensed radioactive material handlers. A review of that database for the defendant's name or business affiliation was not possible as of publication because the defendant's full identity and any associated business entity had not been made public in records available to this outlet.

The Department of Justice has increasingly prioritized prosecutions involving illicit radioactive material transactions in recent years. According to DOJ press releases catalogued in its public database, federal prosecutors have brought charges in similar importation cases in prior years, though cases involving materials with a Russian origin have become more prominent following the expansion of U.S. Sanctions on Russia beginning in February 2022.

The U.S. Customs and Border Protection (CBP) and the Department of Homeland Security's Domestic Nuclear Detection Office (DNDO), now operating as part of the Countering Weapons of Mass Destruction Office (CWMD), are the primary agencies responsible for detecting illicit radioactive shipments at U.S. Ports of entry. Which agency identified the material in this case and at which port of entry, if any, has not been disclosed in available public records.

Sentencing has not yet been scheduled as of the date of this report, based on available court records. Federal guidelines for offenses involving radioactive materials vary significantly depending on the nature of the isotope, the quantity involved, and the intended use, factors that will likely be addressed in sentencing filings, which are public documents accessible through the federal PACER court records system.

Key facts that remain unknown as of publication include the defendant's full name, the specific court docket number, the radioactive isotope or isotopes in question, the quantity of material sold, the names or categories of buyers, the import pathway used, and whether any co-conspirators have been charged or are under investigation. The sentencing memorandum, once filed, and the plea agreement, which is a public court document under federal rules, would answer several of these questions. A search of the PACER federal court records system using the defendant's name or district court would provide additional detail once those records are publicly indexed.
