RAE Systems- GammaRAE II R Radiation Detector / Dosimeter.

The GammaRAE II R is two instruments in one: it has the rapid response of a detector and the accurate dose measurement of a dosimeter. It is designed specifically to meet the needs of first responders.

This instrument contains two separate sensors. The Cesium Iodide (CsI) scintillator provides a fast, two-second response to radiological threats, while the energy-compensated PIN diode provides high dose rate range coverage and accurate dose measurements.

GammaRAE II R alerts the wearer with a loud audible alarm, big, bright flashing LEDs, and a built-in vibration alarm. For stealth operations, users can disable each alarm individually.

Immersible (IP67) design makes for reliable operation in wet environments and easy decontamination. IS certification permits operation in potentially flammable/explosive environments. 

The GammaRAE II R accumulates accurate total dose. Stored dose data can be cumulative or reset for each use period.
