Description

Gamma-ray mass attenuation coefficients have been calculated theoretically for 10CaO-xPbO-(90-x)silica gel waste and 10SrO-xPbO-(90-x)silica gel waste glass systems (where x = 20, 25, 30, 35, 40 and 45 mol%) by using WinXCOM program developed by National Institute of Standards and Technology. Then, the results were obtained further used to calculate half value layer and mean free path values. It was found that the 10CaO-xPbO-(90-x)silica gel waste glass system have higher values of mass attenuation coefficients and lower values of half value layer than 10SrO-xPbO-(90-x)silica gel waste glass system for most of gamma ray energy at 662, 1173, 1332 keV. Moreover, the density, molar volume, elastic moduli, Debye and softening temperature were applied to study the structural properties of both glass systems.
