Paper Title:
Gamma-Rays Absorption Studies of PbO-SiO2 Glass System
  Abstract

Mass attenuation coefficient, total interaction cross-section and effective atomic number of xPbO:(100-x)SiO2, where 30 x 70 (% weight), glass system have been investigated at 662 keV on the basis of the mixture rule. The results are in good agreement with the theoretical values, calculated by WinXCom. The mass attenuation coefficient increases with PbO content, due to higher probability of photoelectric absorption in glass. However, Compton scattering gives dominant contribution to the total mass attenuation coefficient for the glass samples studied. The shielding properties of the glass samples are also better than ordinary shielding concretes and commercial window glasses. These results indicate that the glass systems prepared in this study has a potential to be used as radiation shielding materials.
