U.S. Agencies Remove High-Risk Radioactive Source from Guatemala, Bolstering Homeland Security

The National Nuclear Security Administration (NNSA) and the U.S. Defense Threat Reduction Agency (DTRA) successfully removed a radioactive cobalt-60 source from a facility in Guatemala on August 27, 2026. This interagency mission aims to strengthen U.S. and global radiological security by preventing high-risk materials, which could be used to create a 'dirty bomb,' from falling into the wrong hands. The action aligns with the Trump Administration's 2026 Counterterrorism Strategy.
