WebDescribe what occurs in a Photoelectric interaction. The incident x-ray photon energy must be equal to or greater than the orbital binding energy. The incident x-ray photon interacts with the inner shell electron of a tissue atom and removes it from orbit. WebPhotodisintegration: occurs when the incident x-ray is directly absorbed by the nucleus. The x-ray disappears and nuclear fragment are released. Compton scattering: definition Compton scattering: Interaction between an x-ray and a loosely bound outer-shell electron that results ionization and x-ray scattering. Compton effect: definition
