Abstract
The mass attenuation coefficient (μ/ρ), effective atomic number (Z eff), effective electron density (N e, eff) and half-value layer (HVL) of xR mO n:(1 - x)SiO 2 glass system (where R mO n are Bi 2O 3, PbO and BaO, with 0.3 ≤ x ≤ 0.7 is fraction by weight) have been calculated by theoretical approach using WinXCom program in the energy region from 1 keV to 100 GeV. Also, the HVL of these glass samples has been compared with some standard shielding concretes. The variations of μ/ρ, Z eff, N e,eff and HVL with energy are shown graphically only for total photon interaction. It has been observed that the value of these parameters has been changed with energy and composition of the silicate glasses. The better shielding properties of glass samples were obtained compared with some standard shielding concretes. These results indicated that glasses in the present study can be used as radiation shielding materials. © 2011 Published by Elsevier Ltd.
