The effect of some modifier oxides on the radiation shielding properties of zirconia doped sodium borosilicate glasses

The effect of some modifier oxides (MO) which are Li2O, MgO, ZnO and CaO on the radiation shielding features of B2O3-SiO2-Na2O-ZrO2-MO (BSNZ-MO) glasses were studied by using Geant4 Monte Carlo and the results were theoretically compared by using Phy-X/PSD software between 0.1 MeV and 10 MeV energies. BSNZ-Zn has the highest mu and mu/rho values whereas BSNS-Li has the lowest mu and mu/rho values. The HVLs and TVLs of BSNZ-Zn are the smallest among the BSNZ-MO glasses. The Z(eff) values of BSNZ-MO glasses change in order of BSNZ-Li < BSNZ-Mg < BSNZ-Ca < BSNZ-Zn. The Neff values of BSNZ-MO glasses vary like Zeff values except for 0.4 MeV-3 MeV photon energies. The TMSPs are the lowest for BSNZ-Zn and they are the greatest for BSNZ-Li for protons, alpha particles and heavy carbon ion. The R values of electron are the maximum for BSNZ-Mg and they are minimum for the BSNz-Zn. Besides, The FNRC of the BSNZ-Li has the greatest whereas the FNRC of the BSNZ-Mg has the lowest among the BSNZ-MO glasses.

Automated summary

The effects of Li2O, MgO, ZnO, and CaO on the radiation shielding properties of BSNZ-MO glasses were studied. BSNZ-Zn demonstrated the highest shielding performance, while BSNZ-Li showed the lowest. BSNZ-Zn had the smallest HVL and TVL among all the glasses. The Z(eff) and Neff values of BSNZ-MO glasses varied with different modifier oxides. BSNZ-Zn exhibited the best TMSP for protons, alpha particles, and heavy carbon ions, while BSNZ-Li had the worst. The R values for electrons were highest for BSNZ-Mg and lowest for BSNZ-Zn. Moreover, BSNZ-Li had the highest FNRC, while BSNZ-Mg had the lowest among the BSNZ-MO glasses.
