GAO Issues new Report: HIGH-RISK RADIOACTIVE MATERIAL Opportunities Exist to Improve the Security of Sources No Longer in Use
| November 2023HIGH-RISK RADIOACTIVE MATERIAL Opportunities Exist to Improve the Security of Sources No Longer in Use “Radioactive sources” refers to nuclear materials that emit radiation and are sealed in containers that are specifically designed for use in medical, industrial, or research applications. For example, cesium-137 is widely used in a device that irradiates donor blood to make it safer for transfusions.These radioactive sources can only be used for a defined period—based on radioactive half-life—but some users delay disposal, leaving sources vulnerable to theft. Cost and difficulty of disposal are 2 of the causes we found for delays.Our recommendations are for federal agencies to incentivize users to promptly dispose of radioactive sources. |

| What GAO Found Licensees of high-risk radioactive sources may delay disposing of sources that are in their possession but no longer in use (i.e., disused) for a variety of reasons. For example, the U.S. Nuclear Regulatory Commission (NRC) does not require licensees to dispose of radioactive sources unless a licensee is terminating all activities under its license at specific locations. In addition, some high-risk sources containing radioactive materials that have a long life cycle, including cesium-137 and americium-241, have limited disposal pathways that may require government assistance or may not have a viable disposal pathway at all. Specifically, sources used in the oil and gas industry that contain americium-241 of foreign origin currently have no permanent disposal pathway, leaving them vulnerable to loss or abandonment. Disused High-Risk Radioactive Sources at a Source Processing Facility GAO identified leading practices supported by key entities—such as the International Atomic Energy Agency—that are not reflected in NRC requirements and could help address some disposal challenges. These practices include tracking sources, imposing limits and fees on possession, or collecting financial assurances at the time a source is purchased to offset later disposal costs. Assessing adoption of these leading practices nationwide may more broadly incentivize timely disposal, potentially reduce overall cost to the government, and reduce the risk that radioactive sources could be used in a dirty bomb.To read more about the Study and its recommendations, click here.
