The Domestic Nuclear Detection Office (DNDO) and its law enforcement partners in New York earlier this month tested three prototypes of radiation detection systems at the Belmont Stakes leg of the Triple Crown horse racing series. The systems consisted of two prototypes of the Stand-Off Radiation Detection System (SORDS), which is designed to detect and identify radiation sources from a mobile platform at a long distance, and one prototype of the Roadside Tracker (RST), which is designed to detect and identify sources of illicit materials in vehicles traveling at speed over multiple lanes of traffic. One SORDS unit was supplied by Raytheon [RTN] and the other by Science Applications International Corp. [SAI]. The RST is being developed by the Energy Department’s Oak Ridge National Laboratory. DNDO worked with the Nassau and Suffolk County police departments in the demonstration, part of the agency’s broader effort to actively engage federal, state, and local partners to utilize and assess the new radiological and nuclear detection systems. Currently, police officers conduct radiological and nuclear scanning operations at special events using handheld or backpack detectors.
