Energy imparted, energy transferred and net energy transferred [PDF]

open access: yesPhysics in Medicine and Biology, 1983
The ICRU-defined non-stochastic quantity absorbed dose is related to the stochastic quantity energy imparted. In this paper the corresponding stochastic quantities energy transferred and net energy transferred are defined as precursors for kerma and collision kerma, respectively. This forms a rational fundamental framework for radiation dosimetry which
