GammaRAE II Personal Gamma Radiation Detector Rental $60.00 $145.00 $375.00

GammaRAE II is the first personal radiation detector (PRD) to provide rapid detection of gamma ray sources even in potentially flammable environments. Certified intrinsically safe and water-immersible for chemical decontamination purposes, the GammaRAE II can be safely used in more environments than any other PRD.

The sensitive Cesium Iodide (CsI) scintillator of the GammaRAE II provides a fast, two-second response to radiological threats. GammaRAE II alerts the wearer with a loud 85+ dB audible alarm, big, bright flashing LEDs, and a vibration alarm. For stealth operations, law enforcement personnel can disable each alarm individually.

The GammaRAE II accumulates approximate dosage. Dosage data stored can be cumulative or cleared and reset for each use period. IS Certification permits operation in potentially flammable/explosive environments.
