The U.S Department of Homeland Security (DHS) established the System Assessment and Validation for Emergency Responders (SAVER) Program to assist emergency responders making procurement decisions. Located within the DHS Science and Technology Directorate (S&T), the SAVER Program conducts objective assessments and validations on commercial equipment and systems, and provides those results along with other relevant information to the emergency responder community. To better understand the different types of SAVER documents, refer to the SAVER Definitions publication.

Personal radiation detectors (PRDs) are small electronic devices worn by emergency responders. These devices alert the wearer to slight changes in the background radiation level for the purpose of detecting and interdicting the illicit movement of radioactive material. Some PRDs, known as spectroscopic personal radiation detectors (SPRDs), also measure the energy spectrum of radiation to identify the radionuclide present.

Individuals who carry explosives or objects that contain explosives are likely to be contaminated with traces of explosives, microscopic residues that are invisible to the naked eye. Handheld explosive trace explosives detectors are small and light enough to be held and operated in the hand, and can be used to detect homemade, commercial, or military explosives, although not all detectors can detect all three types of explosives. In addition to explosives, some detectors can also detect narcotics, chemical warfare agents, or toxic industrial chemicals. Included report: Handheld Explosive Trace Detectors TechNote.
