APPLICATION NOTE 2236
Gamma-Photon Radiation Detector

A PIN photodiode, four low-noise op amps and a comparator are used to detect individual photons of gamma
radiation. The schematic, design considerations and component selection are discussed.


The circuit of Figure 1 includes a PIN photodiode that detects individual photons of gamma radiation. When a
photon strikes a depletion region created by reverse bias on the photodiode, it produces a small amount of
charge in proportion to the photon's energy. The resulting signal is then……
