 Radiation
Detector This detector is an industrial standard model of a Geiger-Müller tube with a thin mica output window. It is factory-calibrated using a pulse generator and is typically +-15% of the full scale relative to Cesium 137. It carries out detections in milliroentgens/hour and in events/minute (cpm) in three different measurement intervals. The unit is protected by an antisaturation circuit up to a value equivalent to 100 times the maximum reading in the greatest interval. Radiation detection is indicted by the hand moving on the graduated scale, a blinking LED and an audible beeper. |
