Question

What is the difference between Compton scattering and photoelectric absorption? *

Compton scattering generates two photons; PEA generates multiple photons and/or electrons.

Compton scattering is mostly forward directed; PEA replaces a valence electron

Compton scattering removes a valence electron; PEA involves absorption of a photon, electron cascade, and emission of characteristic x-rays/secondary electrons.

Compton scattering is primarily used to generate contrast in mammography; PEA is primarily useful in x-ray

Answer 1

Answer:

Compton scattering occurs when a photon interacts with an outer orbital electron, which receives kinetic energy and recoils from the point of impact. ... As with photoelectric absorption, Compton scattering results in the loss of an electron and ionization of the absorbing atom. Scattered photons travel in all directions.
