The Guardian Defender® and Guardian Predator® Portable Radiation Search Tools (PRST) are intended for use by safeguard inspectors, law enforcement, first responders, and military personnel for radiation source search and is ideally suited for military and law enforcement agencies tasked with counter-terrorism, for facilities inspections, and for emergency response teams. The Guardian Defender®; and Guardian Predator® are extremely easy to use, all-in-one tool that reports immediate “red light/green light” results. Configuration parameters can be customized quickly and easily for mission specific purposes. The Guardian Defender® and Guardian Predator® PRST come several configurations: backpack, a doffable vest-overlay, or custom user defined packing.

Depending on user requirements and configuration, the system is designed to distinguish between special nuclear material (SNM), naturally occurring radioactive materials (NORM), radiation dispersal devices (RDDs), medical isotopes, and industrial isotopes in a way that minimizes operator interaction with the system controls and indicators.
The Guardian Detection System Kit can be remotely connected to a Notebook PC, PDAs and cell phones. Mission critical data can be sent to and monitored from a command and control center and a central reach-back facility.
