KERMA,

1 abbreviation for kinetic energy released in the medium, a quantity that describes the transfer of energy from a photon to a medium as the ratio of energy transferred per unit mass at each point of interaction.

2 abbreviation for kinetic energy released in matter, a unit of quantity referring to the kinetic energy transferred from photons to charged particles, such as electrons in Compton interactions, per unit mass. The SI unit for the KERMA is the gray, and the special unit is the rad.
