Utilizing additional radiation detection equipment, the Corporal conducted a systematic survey of the area and determined that a Cs-137 radioactive source was emitting radiation from beneath the ground. This successful recovery highlights the DPS Rad/Nuc Unit’s specialized partnerships with local, state and federal agencies to conduct emergency response and hazardous material recovery operations.
