Photon and Neutron Shielding Competence of SnO2 – Reinforced with 22Na2O – 15B2O3 – 45P2O5 – (18 - x) K2O Bioactive Glasses.
Abstract
The shielding capabilities of 22Na2O –15B2O3 –45P2O5 – (18 – x) K2O – xSnO2 metal oxides with different mixing ratio (x = 0, 2, 4, 6, 8 and 10 mol %) from S1-S6 was determined using winXCOM software. S1-S6 bio-glasses' photon and neutron attenuation capabilities have been compared to those of conventional concrete. The results of the simulation show that as energy changes, the MAC values of all the glass samples change in a similar way. As a result, the MAC values tend to be in the order of S1 < S2 < S3 < S4 < S5 < S6 for the majority of the energy spectrum. Based on the MAC values, it can be hypothesized that an increase in the SnO2 content of the glass leads to increase in the effective electron density and mass density of the material thereby enhancing its capacity for photon attenuation. Similar to the MAC, the linear attenuation coefficient (LAC) magnitude varied with energy in accordance with the various photon interaction modes. S1-S6's LAC maximums were 0.08, 0.45, 0.59, 0.71, 0.80, and 0.92, respectively. LAC values also tend in the same direction across all glass species; however, the magnitude trend is in the following order: S6 > S5 > S4 > S3 > S2 > S1.The greatest HVT was acquired for all glass tests with values 65.56, 13.28, 11.18, 10.26, 9.81, and 9.16 cm for S1-S6 accordingly. For S1 to S6, the magnitudes of the maximum values of MFP were 12.31, 2.22, 1.69, 1.42, 1.25, and 1.08 cm, respectively. The findings of MAC, LAC, and HVT are in agreement with the fact that the SnO2 content decreased the magnitude of MFP, as the Sn molar concentration increased in the glass samples. The lower MFP, HVT, and higher MAC values are directly attributed to the rise in Zeff. As a result, the calculated radiation interaction parameters revealed that S6 outperformed the other five bioactive glasses in this study as a photon, proton, and neutron absorber. In general, photon shielding applications may benefit more from the studied bioactive glasses than conventional concrete.
