Its probability is proportional to Z³/E³, making it the primary mechanism responsible for subject radiographic contrast and differential tissue absorption. Its probability depends solely on material physical density and is completely independent of the atomic number of the absorbing medium. It occurs predominantly at very high photon energies above 1.022 MeV and results in forward-scattered secondary photons that degrade image contrast. The incident photon loses only a fraction of its kinetic energy to an outer-shell electron, continuing along a deflected trajectory.
