Kerma

Applicable units are those of quantitykind:Kerma

"Kerma" is the sum of the initial kinetic energies of all the charged particles liberated by uncharged ionizing radiation (i.e., indirectly ionizing radiation such as photons and neutrons) in a sample of matter, divided by the mass of the sample.

For indirectly ionizing (uncharged) particles, $K= \frac{dE_{tr}}{dm}$, where $dE_{tr}$ is the mean sum of the initial kinetic energies of all the charged ionizing particles liberated by uncharged ionizing particles in an element of matter, and $dm$ is the mass of that element.
