GammaGuard is a system of radiation detectors designed for First Responders and Homeland Security. The system includes alpha, beta, gamma radioactive contamination detectors, high sensitivity gamma detectors, neutron detectors as well as a radiation detector that indicates the direction of the source of radiation. All of our instruments can operate in stand-alone mode or connect to our GammaGuard app, which provides a rich user interface and enhanced functionality. Read more about our app here.
