Darpa seeks to expand real-time radiological threat detection to include other dangers building on sigma’s advanced capability to sniff out illicit radioactive and nuclear materials, sigma+ program aims to create additional sensors and networks to detect biological, chemical, and explosives threats.
For the purposes of the following discussion, the threats to homeland security from nuclear and radiological terrorism are grouped into the following three categories. A radiological attack is the spreading of radioactive material with the intent to do harm radioactive materials are used every day in laboratories, medical centers, food irradiation plants, and for industrial uses.
Defining the threats seizing an intact nuclear weapon experts typically classify nuclear and radiological terrorism into four threat categories first, a non-state actor such as a terrorist or criminal or a group of terrorists or criminals could acquire a nuclear weapon from an arsenal of a nuclear-armed state. Radiologic threat agents are radioactive materials released that have adverse health effects radiation emergencies may be intentional or unintentional unintentional radiologic emergencies include nuclear blast, nuclear reactor accidents, and transportation accidents like a spill of radioactive material from a truck or train.
