WebGamma decay is one type of radioactive decay that a nucleus can undergo. What separates this type of decay process from alpha or beta decay is that no particles are ejected from the nucleus when it undergoes this type of decay. Instead, a high energy form of electromagnetic radiation - a gamma ray photon - is released. Gamma rays are simply … Web6 mei 2024 · Gamma rays interact with matter in three main ways: the photoelectric effect, Compton scattering, and pair production. The photoelectric effect dominates at the low end of gamma ray energies (below 50 keV). In this situation, the gamma photon causes the ejection of an electron from an atom through a transfer of energy.
