Abstract:In this paper, the method of calculating X-ray photoelectric absorption coefficient andCompton scatter coefficient for matter is described- As several examples, both the photoelectric absorptionand Compton scatter coefficients of polytetrafluoroethylene, a double-base propellant and human being'sfresh bone, in the X-ray energy range of about 1 keV to l MeV, are calculated.
Keywords:X-ray  Photoelectric effect  Absorption coefficient  Compton scattering  Scattering coeffieient
