SemeaTech's 3cc Cesium Iodine Gamma Sensor Module 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 ( 0.01 μSv/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).
