Photodisintegration Definition & Meaning - Merriam-Webster

WebMar 6, 2016 · Beam attenuation occurs as a result of the photon interactions with the atomic structures that comprise the tissues. Two distinct processes occur during beam attenuation: absorption and scattering. Absorption As the energy of the primary x-ray beam is deposited within the atoms comprising the tissue, some x-ray photons are completely absorbed. 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
