Gamma Detectors

Exosens Group (Photonis Group)

In Gamma detectors, the gamma radiations produce electrons by interacting with the cathode material and the filling gas.
These electrons ionize the gas and the charge carriers are collected by the electrodes. The resulting anode pulse is detected by a load circuit. The primary electrons are created by several interaction mechanisms:
- Photoelectric effect
- Compton scattering
- Pair production
