U.S. NNSA and DTRA Remove High-Risk Cobalt-60 Radioactive Source from Guatemala
The U.S. National Nuclear Security Administration (NNSA) announced on August 27 that, in cooperation with the U.S. Defense Threat Reduction Agency (DTRA), it has removed a high-risk cobalt-60 radioactive source from a facility in Guatemala and transported the associated components to a secure storage location in the United States. This operation aims to reduce security risks associated with radioactive materials and prevent high-activity radioactive substances from being illegally acquired or misused. According to reports, cobalt-60 can be used in medical equipment for cancer treatment, but high-activity radioactive sources, if improperly managed, may pose radiological safety hazards. In May of this year, an NNSA Los Alamos National Laboratory team, in cooperation with relevant Guatemalan agencies, worked on a decommissioned U.S.-manufactured cobalt-60 teletherapy...

A Category IV Cobalt-60 (Co-60) radioactive source retired in Huangshi
Recently, under the coordinated deployment and on-site supervision of the Huangshi Municipal Ecological Environment Bureau in Hubei Province, a retired Category IV Cobalt-60 (Co-60) radioactive source was transported in a closed loop by a professionally qualified vehicle and safely delivered to the Hubei Provincial Urban Radioactive Waste Repository, where it was permanently sealed in a standardized manner. The collection and storage process for this waste source followed standard procedures with meticulous control, and no readings exceeding limits, equipment loosening, or other safety anomalies occurred throughout the entire transport process. It is understood that this Cobalt-60 radioactive source was originally the core component of a level gauge supporting an enterprise's kiln production line. As the production line was dismantled and scrapped, the related equipment ceased operation, increasing the safety management pressure of the idle radioactive source. Upon receiving the enterprise's disposal application, the Huangshi Municipal Ecological Environment Bureau...
