Mathematical description and method of calculation of fluctuations in energy absorption in small volumes of material irradiated by ionizing particles
Abstract
Closed representations are obtained for the density of the distribution and the moments of the absorbed energy in an isolated region of an irradiated absorber. It is shown that, for a broad class of problems (mainly microdosimetric), these quantities are expressed in terms of the differential flux densities of charged particles integrated over the angles and defined energy functions depending on the dimensions of the region and the material present there. The method of calculation deriving from the given representations is discussed.
