GG2W High Sensitivity Gamma GM Detector

he GG2W Intelligent Gamma Probe is an integrated real-time Gamma radiation monitoring device that provides accurate indication of ambient Gamma radiation over a wide range. The GG2W uses a pair of halogen quenched Geiger Müeller tubes for sensitivity to ambient gamma radiation levels. The GM tubes are operated using a “Time-To-Count” method which removes the limitations associated with traditional ‘constant bias’ GM tube circuits.
