Abstract

45S5 bioglass system is a sol-gel specifically composed of SiO2+CaO+Na2O+P2O5 that has superior features for bone regeneration. In this article, the effects of MgO addition (0, 1, 2, 3, and 5 mol %) on the radiation attenuation properties of 45S5 bioglass system were investigated. For photons beam, we determined the linear attenuation coefficient (LAC), gamma dose rate (GDR), and effective atomic number (EAN). Moreover, the total stopping power and projectile range were calculated for charged particles such as beta (electron), proton (hydrogen ion), and alpha (helium ion). Finally, the attenuation properties of 45S5+MgO bioglass system were studied in detail for thermal and fast neutrons. The obtained results indicate that the maximum LAC was around 0.2175 cm−1 at 0.6 MeV for the studied bioglass system. The highest GDR was noted at 10 MeV in the distance of 1 mm with the value of 1.09 × 108 R/h for 45S5+MgO1 bioactive glass. For neutron attenuation, we found that the removal cross-section (RCS) values were 0.0894, 0.0896, 0.0898, 0.0901, and 0.0904 cm−1 for the studied bioactive glasses of 45S5+MgO1, 45S5+MgO2, 45S5+MgO3, 45S5+MgO4, and 45S5+MgO5, respectively. It was concluded that the MgO addition has an insignificant influence on the radiation attenuation properties of the 45S5 bioglass system.
