Hamamatsu - Model C12137 Series - Radiation Detection Modules Brochure

The C12137 series is a radiation detection module containing a scintillator and MPPC® (multi-pixel photon counter) designed to detect gamma rays from 137Cs (Cesium-137) and the like. The scintillator converts incident gamma rays into visible light, and the MPPC detects the light down to extremely low light levels to measure low-energy gamma rays with high accuracy. The signal processing circuit and A/D converter are housed in a compact case. The modules provide a USB or RS-232C interface. The products include sample software with functions for setting measurement conditions, acquiring and saving data, and drawing graphs, etc.
