Attenuation of Radiation - University of Tennessee

The binding energy is a few electron volts and is negligible compared to the energies of the gamma rays that may be on the order of a few million electron volts. The kinetic energy given the electron by the gamma ray then gives up its energy to the material in which it is located by interacting with the outer electrons of the atoms of the material.
