"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. " - Photodisintegration interactions

Photodisintegration interactions

Photodisintegration (also called phototransmutation, or a photonuclear reaction) is a nuclear process in which an atomic nucleus absorbs a high-energy gamma ray, enters an excited state, and immediately decays by emitting a subatomic particle.
