Symbol: K
Definition: quotient of dEtr by dm where dEtr is the sum of the initial kinetic energies of all charged ionizing particles liberated by uncharged ionizing particles in a mass dm of material

K = dEtr/dm

Note 1 to entry: The unit for kerma is gray (1 Gy = 1 J kg−1).

Note 2 to entry: Kerma is derived from “kinetic energy released per unit mass”.

Note 3 to entry: In the case where the material is air the name is air kerma.
