Sensor Tech Handheld Radiation Monitor

Handheld Radiation Monitor by Sensor Technologies Engineering. The HRM is a small, self-contained gamma ray and thermal neutron radiation detector for use in the interdiction and localization of nuclear materials. It was specifically designed for operators who need to quickly and discreetly detect and locate a threat device or radiological materials in an unpredictable radiation background. The high sensitivity of the HRM is made possible by the use of a high-quality photomultiplier tube and a cesium iodide scintillator combined with a high-pressure Helium-3 filled proportional counter. It is the size of a flashlight and is intended to be handheld or worn on the operator’s belt, leg, or arm in the nylon holster.
