Radiological Security


The  program collaborates with domestic and international partners to address the threat of illicit use of high-priority radiological materials in the United States and abroad. The Radiological Security program accomplishes its mission by removing and disposing of excess or orphaned radioactive sources; promoting the replacement of radioactive sources with non-isotopic technologies, where feasible; and increasing security where high-priority radiological materials are still required.

Key initiatives that fall within the Radiological Material Removal program include:

  • Working in cooperation with Federal, State, and local agencies, and private industry to recover and permanently dispose of disused and unwanted radioactive sources in the United States.
  • Training law enforcement personnel, on site guard forces and Radiation Safety Officers on how to properly respond to the attempted theft of a radioactive source at its Alarm Response training course at Y-12.
