In this study, the shielding properties of 20.15 [(2.038 + x)SiO2-(1.457-x)Na2O]-2.6P2O5-25.73CaO-1.22MgO, where 0<x<1, in steps of 0.125 (mol%)glasses have been examined to be applied in radiation protection applications. Therefore, we used the MCNP5 code to simulate the mass attenuation coefficient for nine glass samples. The obtained simulated mass attenuation (μm) results were compared with those obtained theoretically by the XCOM database within photon energies 0.03–20 MeV. The simulated μm results were found to be in good agreement with the XCOM received data. The linear attenuation coefficients(μ), the effective atomic number (Zeff), half-value layer (Δ0.5), and mean free path (MFP) were calculated based on the simulated μm. The μm was decreased with the increase of SiO2 concentrations and the increase of gamma-ray energy. Finally, it is found that the G9 glass with 60mol% SiO2 and 9.21 mol% Na2O has superior gamma-ray shielding effectiveness due to its higher values of mass attenuation coefficient, effective atomic number, and electron densities. •Gamma-ray shielding properties of SiO2–Na2O–P2O5–CaO–MgO have been studied.•The μm results were simulated at 0.03–20 MeV, and compared with WinXCom values.•The G9 with 60mol% SiO2 has the best effectiveness shielding against gamma photons.•The data is useful in radiation protection and other fields.
