What is photoelectric absorption?
If the formation is very dense or if the atomic number is very high, the formation will contain a large number of electrons. The gamma rays will interact with many of these electrons, losing energy each time. Some gamma rays will lose so much energy, they will become low-energy gamma rays.When a low-energy gamma ray interacts with an electron, the electron is ejected from the atom’s orbital shell. The energy of the gamma ray is transferred to the electron. This energy is a function of the atomic number (Z).
