Nuclear Terrorism
Published in Robert A. Burke, Counter-Terrorism for Emergency Responders, 2017
DHS has made important strides in improving the detection technologies, strengthening the international partnerships, and increasing the number of law enforcement personnel trained in detection-related equipment. DHS also continues to build upon its substantial expertise in nuclear forensics, the ability to trace nuclear materials and weapons to their source. Radiation Portal Monitors: DHS has worked with U.S. Customs and Border Protection (CBP) to deploy Radiation Portal Monitors and other radiation detection technologies to seaports, land border ports, and mail facilities around the world. Today, these systems scan 100% of all containerized cargo and personal vehicles arriving in the United States through land ports of entry, as well as over 99% of arriving sea containers.Securing the Cities: DHS plans to expand the Securing the Cities (STC) initiative, designed to enhance the nation's ability to detect and prevent a radiological or nuclear attack in the highest risk cities, to include additional urban areas while continuing to support efforts in existing STC regions. For example, through STC, approximately 19,450 personnel in the New York City region have been trained in preventive radiological and nuclear detection operations and more than 8,800 pieces of radiological detection equipment have been funded. The program expanded to Los Angeles/Long Beach in 2012 and to the National Capital Region in 2014.

Radiation portal monitors, typically referred to as RPMs, are ubiquitous for detecting gamma- (γ-) and neutron-emitting radionuclides (RNs) across industrial, civil nuclear power generation, and security settings. With applications ranging from identifying potential contamination on plant workers to detecting RNs within scrap metal consignments, and screening vehicles, cargo, and containers for illicit materials at international borders, RPMs form a crucial component of the national public health and security infrastructure.[1]
