Model 3cc CsI -Cesium Iodine Gamma Sensor
SemeaTech`s 3cc Cesium lodine Gamma Sensor consists of a cesium iodide crystal, a photodiode, and a high-gain preamplifier that can be used to measure X and γ radiation from 50keV to 3MeV. It features high sensitivity and an instant response time (of about a second) to a very minor change of X and γ (0.01μSv/h). The sensor is housed in a 45x24x18±0.5mm metal housing with a cable of approx, 55mm as the connection interface. The connector is a 4-pin MOLEX PicoBlade 1.25mm (.049``) connector (reference Molex connector, part No.51021-0400).
