VideoRay Radiation Sensor

The radiation sensor mounts to the bottom of the Pro 4 and can read, plot, and trigger an alarm upon the detection of radiation. The system is very sensitive to Gamma radiation and high energy X-Rays. The sensor is not designed to detect Alpha or Beta particles because these particles will not penetrate the pressure housing. Gamma Sensitivity 10 Kev. Cesium Calibration Tube calibrated to Cesium 137 +/- 5% (MIL-STD-45662).
