What does Coherent Scatter primarily involve in terms of energy?

Coherent scatter primarily involves very low energy radiation interactions, which is the reason why this answer is considered correct. In coherent scattering, also known as classical scattering, low-energy photons interact with matter without causing Ionization. Instead, the photons are scattered elastically, meaning they retain their energy but change direction.

This phenomenon typically occurs with photons that have energies in the range of a few keV, which is characteristic of non-ionizing radiation. Since the energy of the interacting photons is relatively low, coherent scatter is most significant in materials with atomic numbers, such as biological tissues, where these interactions can occur frequently without absorption.

Understanding this concept is important in radiation protection because the effects of low-energy radiation scattering can influence the distribution of radiation dose within tissues, particularly in diagnostic imaging scenarios. This knowledge helps radiologic technologists and health physicists to manage and minimize the dose to patients while maintaining image quality.
