E)All the above processes can take place.

Question

Quizplus · Accepted Answer

All the mentioned processes can take place when gamma ray interacts with a material. Depending on the energy of the gamma ray, any of these processes may occur. When a gamma ray passes through a material, it may cause photoelectric effect, Compton scattering, or pair production, or it may pass through the material unchanged. The probability of each process occurring depends on the energy of the gamma ray and the atomic properties of the material.
