Total reflection coefficients of low-energy photons presented as universal functions

摘要: The possibility of expressing the total particle and energy reflection coefficients low-energy photons in form universal functions valid for different shielding materials is investigated this paper. analysis based on results Monte Carlo simulations photon reflection by using MCNP, FOTELP, PENELOPE codes. normal incidence narrow monoenergetic beam unit intensity initial energies from 20 keV up to 100 considered, from plane homogenous targets water, aluminum, iron are determined compared. representations albedo on energy, probability large-angle photon scattering, mean number scatterings examined. It is found out that only rescaled dependent mean have these by applying least square method.
