Abstract

This study investigated the glass density and gamma shielding capacity of xAl2O3–40SiO2–5BaO–10Bi2O3–20ZrO2-(25-x)Na2O glass system, where x = 0, 5, and 10 mol%. This glass system was synthesized and the density of the samples increased from 2.92 g/cm3 to 3.14 g/cm3 as the Al2O3 content rose from 0 to 10 mol %.
The mass attenuation coefficients ranged from 0.0316 to 38.9421 cm2/g for AlSN–Zr1, 0.0315–38.8504 cm2/g for AlSN–Zr2, and 0.0311–37.0391 cm2/g for AlSN–Zr3. The mean free path and half-value layer for the gamma energy spectrum were approximately 7.54–0.01 cm and 10.87–0.01 cm for AlSN–Zr1, 7.19–0.01 cm and 10.38–0.01 cm for AlSN–Zr2, and 7.14–0.01 cm and 10.31–0.01 cm for AlSN–Zr3, respectively.
The effective Z values range from 14.65 to 55.13 for AlSN–Zr1, 14.41–55.74 for AlSN–Zr2, and 14.10–55.01 for AlSN–Zr3. Moreover, the Al2O3 content incorporation reduced photon buildup factors and improved the photon shielding performance of the glass system. Based on the results, AlSN–Zr3 demonstrated the potential to replace conventional shielding materials such as glasses, concrete, and rocks. These glasses a promising candidate for durable gamma-ray shielding applications.
