HRM
The Handheld Radiation Monitor (HRM) is a small, self contained gamma ray and thermal neutron radiation detector for use in the interdiction and location of nuclear materials. It was specifically designed to be easily used by trained security forces and emergency responders. The instrument uses a miniature photomultiplier tube and solid state scintillation detector combined with a high pressure Helium-3 filled proportional counter. The HRM is the size of a flashlight, and is intended to be handheld or worn on the operator’s belt in the nylon holster provided.
