C)photoelectric interactions.
D)Bremsstrahlung interactions.

Question

Quizplus · Accepted Answer

Photoelectric interactions occur when a photon's energy is completely transferred to an inner shell electron within an atom, causing it to be ejected and produce ionization. This is the dominant mechanism for photon absorption at low energies (below a few hundred keV) within the body. Compton interactions and Bremsstrahlung interactions are more important at higher energies and are less dominant than photoelectric interactions. Characteristic interactions are a type of photoelectric interaction, but they are not the dominant mechanism for photon absorption within the body.
