Gamma Radiation - an overview ScienceDirect Topics

WebGamma rays are the highest energy photons (shortest wavelength, highest frequency), arising out of nuclear events during radioactive decay. For in vivo applications, the best gamma rays are of low energy (100–511 keV) because they can penetrate tissues. Webgamma rays used for imaging are produced when a positron meets an electron inside the patient’s body, an encounter that annihilates both electron and positron and produces two gamma rays travelling in opposite directions. By mapping gamma rays that arrive at the same time the PET system is able to produce an image with high spatial resolution.
