| Abstract: |
Building on our previous study of structural, and electrical properties of Na2O-B2O3-P2O5 work investigates their γ-ray shielding performance. Glasses with compositions 30Na2O - (70-y) B2O3-y P2O5 (where y = 0, 14, 21, and 35 mol%) were analyzed using the Phy-X/PSD software to determine the attenuation and penetration factors of this glass system at different energies. The linear attenuation coefficient (LAC) values were found to decrease exponentially with increasing energy, ranging from 0.124 to 0.089 cm-1 for 30Na2O - 70 B2O3 and from 0.138 to 0.099 cm-1 for y = 35 mol%. The addition of phosphorus pentoxide (P2O5) led to an increase in LAC values from 0.174 to 0.193 cm-1 at 0.662 MeV. The effective atomic number (Zeff) results indicated a higher probability of photon interaction with increased P2O5 content. The maximum Zeff was recorded at 0.284 MeV, with values of 7.46 for NBP1 and 8.92 for y = 35 mol%. The Phy-X/PSD program was also used to calculate the half-value layer (HVL) for the evaluated glasses in the energy range of 0.284-2.506 MeV. The HVL results showed that more gamma rays were shielded at 0.284 MeV, while photon shielding efficiency decreased with increasing energy. The tenth-value layer (TVL) values decreased with higher P2O5 concentrations but increased with higher energy. The phosphate rich glass (y = 35 mol%) exhibited the lowest TVL values (8.401 cm at 0.284 MeV, 11.928 cm at 0.662 MeV, and 16.355 cm at 1.275 MeV) and thus shows an excellent gamma-rays shielding properties. These findings demonstrate that P2O5 incorporation strengthens the glass network and enhances the γ-ray shielding capability, positioning borophosphate glasses as promising lead-free shielding materials.
