Radiation shielding properties of BaO:WO3:Na2O:B2O3 glass system using WinXCom program in the range of 1 keV to 100 GeV: Theoretical calculation

Abstract

The research aimed to study the radiation shielding properties of xBaO-5WO3-15Na2O-(80-x)B2O3 glass system where x = 5, 10, 15, 20, 25, 30 and 35 mol%. The theoretical values calculated using WinXCom program in the range of 1 keV to 100 GeV energy regions. The results of calculation found that the mass attenuation coefficients were increased with increase in BaO concentration and decreased with the increasing energy. Moreover, these glass system at low energies show discontinuities corresponding to photoelectric absorption edges of tungsten and barium. For the partials interaction at the low energies range the photoelectric absorption is the main interaction in these energy regions. At the medium energy regions, the radiation shielding parameters are almost constants dominated by Compton scattering process. In the high energy regions, pair production becomes the main interaction process over the energy. It can also be concluded that the characteristics of radiation shielding parameters for the glasses system depend on different barium in this concentration and the energy regions. The lead equivalent thickness of glass samples show that glass samples increasing trend with increase in concentration of BaO and the experimental are good agreement with theoretical value.
