Cool Gamma Detector Fact

Gamma-ray Detectors

Gamma-ray detection in the energy region above 1 keV involves the measurement of the energy exchange between the incident photon and the mass of the detector. In most cases, it is the kinetic energy imparted to charged particles by the gamma-ray which is lost in the detector and measured in order to obtain knowledge of the incident source spectrum.
