GammaRae II Responder 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.
The GammaRae II Responder 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.
Loud Alarm - GammaRae II Responder 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.
Water Resistant - Immersible (IP67) design makes for reliable operation in wet environments and easy decontamination.
Dosage Accumulation - The GammaRae II accumulates accurate total dose. Dosage data stored can be cumulative or cleared and reset for each use period.
Intrinsic Safety - IS Certification permits operation in potentially flammable/explosive environments.
