Managing Critical Isotopes: DOE Could Better Assess Market Needs and Respond to Risks

What GAO Found The Office of Isotope Research and Development and Production (IRP), within the Department of Energy’s (DOE) Office of Science, produced, sold, and distributed 265 isotopes during fiscal years 2020 through 2025. Many of these isotopes are critical to medical diagnosis and treatment, national security, industrial processes and manufacturing, and quantum science. IRP made over 7,700 isotope shipments, most of which were for medical purposes.
