In this study, the gamma photons shielding parameters of the newly produced (NG1, NG2, NG3 and NG4) and widely used (Window, PbO, Soda and Borosilicate glasses) glass samples were evaluated comparatively. Mass attenuation coefficients (μ/ρ) of the samples under study are computed by MCNPX simulation code and compared to WinXCOM results in the energy range 0.015–15 MeV. Additionally, half value layer (HVL), effective atomic numbers (Z e f f) and electron densities (N e l) of the samples were calculated by the obtained results from WinXCOM and MCNPX. Among the prepared samples, NG4 glass has highest values of μ/ρ and Z e f f, lowest values of N e l and HVL. On the other hand, the μ/ρ and Z e f f values are minimum, N e l and HVL are maximum for Window and Soda glasses. Also, the exposure buildup factor (EBF) values of the samples were evaluated by using the Geometric progression …
