The City of Los Angeles and the Emergency Services Division, Securing the Cities was selected by the Domestic Nuclear Detection Office to implement the Secure the Cities (STC) Initiative, a federally funded grant program from the Department of Homeland Security. As part of this Initiative, the STC was tasked with developing a vigorous Preventative Radiological Nuclear Detection Program to interdict the illicit transportation of radiological/nuclear materials and/or weapons within the region. As part of this program, the STC issues personal radiation detection equipment to Department personnel and provides related training.
