Gamma ray detection module C12137 series

MPPC

High accuracy, High sensitivity, compact radiation detection module 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 date, and drawing graphs, etc. Features - Gamma ray energy discrimination - Modular design for easy integration into devices - Compact and lightweight Detection of low energy gamma rays and energy discrimination The C12137 series is capable of acquiring an energy spectrum as well as providing accurate energy discrimination. 137Cs is known to decay while emitting gamma rays at energies around 662 keV and around 32 keV. Acquiring an energy spectrum down to low energy gamma rays around 30 keV allows determining whether those gamma rays are derived from 137Cs . When the energy of gamma rays entering a scintillator falls to a low level, the light level emitted from the scintillator in response to the gamma rays is also very low. The C12137 series uses a high sensitivity MPPC that allows detecting gamma rays over a wide range.
