The Mechano-Radiation Protection Behaviors of SiO2⋅CaO⋅P2O5⋅Na2O Bioglasses Substituted with ZnO.

Silicate glasses containing sodium, calcium, and phosphorus are known as bioactive glasses, which are utilized in the human body to support and fulfill living tissue functions. These glasses exhibit excellent physical and mechanical properties, making them suitable for radiation shielding applications. This study focuses on investigating the radiation absorption parameters of seven bioglasses. The densities of the samples were found to increase from 2.6383 to 3.2218 g/cm3 as the ZnO increased from 0.0 to 15 mol%. Also, the mass-attenuation-coefficient (i.e., MAC) was calculated via the Phys-X simulation code in the photonic-energy domain of 0.015–15.0 MeV, and the outcomes were compared with XCOM data. The computed MAC values have the following sequential order: MAC_46MBG-0Zn < MAC_65MBG-5Zn < MAC_64MBG-7Zn < MAC_60MBG-15Zn < MAC_45MBG-4Zn < MAC_44MBG-7Zn < MAC_40MBG-15Zn. Other important parameters, such as the half- and tenth-value-layer (i.e., HVL, and TVL), mean-free-path (MFP), and effective-atomic-number (Z_eff), were also determined. Among the bioactive-glasses studied, the bioglass encoded as 60MBG-15Zn, which contains uppermost amounts of silicate and zinc, had the lowest MFP, HVL, and TVL values but the highest Z_eff values. Effective removal cross-section values (Σ_R) were determined to assess the neutron safety effectiveness of the bio-glasses, and the results indicated that 60MBG-15Zn ([ZnO]/[SiO₂] = 0.258) and 40MBG-15Zn ([ZnO]/[SiO₂] = 0.375) had advanced neutron lessening character. The exposure- and adsorption-buildup factor (i.e., EBF and EABF) values were also calculated using the G-P least-square-fit model, which depends on the photon energy and MFP. The bioglasses with higher equivalent-atomic numbers were found to have the lowest EBF, and EABF values. Also, the calculated elastic-mechanical intrinsic of the bio-glasses, including the molar volume (V_m), which increased from 16.680 to 20.128, and the dissociation-energy (G), which varied from 56.012 to 63.771 kJ/cm³ were found to depend on ([ZnO]/[SiO₂] molar ratio.
