Number albedo of low-energy photons for water, aluminum, and iron

Abstract

Number albedo of water, aluminum, and iron for incident photons in the energy range from 20 keV to 100 keV is presented in this paper. The results are obtained through Monte Carlo simulations of photon reflection by using MCNP-4C, FOTELP-2K3, and PENELOPE-2005 computer codes. The calculated values are compared with the classical data published by B. P. Bulatov and his collaborators. The influence of fluorescence yield to the photon number albedo of an iron target at the initial photon energies below 40 keV is detected and analyzed.
