Abstract

Radiation attenuation behaviour of TeO2–ZnO–Bi2O3–Na2O–Er2O3 with the addition of Al2O3 nanoparticles (NP), rice husk fiber (RHF), and rice husk ash (RHA) was investigated using Phy-X/PSD software. The mass attenuation coefficients of the chosen glasses were measured from 0.015 to 3 MeV. The results showed that increasing the RHF concentration of the glasses or decreasing the Al2O3 component of the glass system enhances the mass attenuation coefficient of the material. At low energy, there is a significant difference between the mass attenuation coefficients values of the samples with the lowest and highest Al2O3 content, where the difference is 0.05118 cm2/g at 0.015 MeV. TZNERHF had higher mass attenuation coefficients (0.05402 cm2/g), and TZNETiAl8 had the highest mass attenuation coefficients, with a value of 0.05357 cm2/g at 1.173 MeV. The results showed a decreasing trend in the half-value layer (HVL), tenth value layer (TVL), and mean free path (MFP) when the density increased from 5.12555 to 5.23882 g/cm3 and attenuation ability improved. Subsequently, the influence of Al2O3 on Zeff values became more considerable as Zeff values increased. The shielding qualities of their glass samples are also superior to commercial window glass and common shielding concrete. Thus, the glass samples can be used with excellent advantage as radiation shielding materials. The findings showed that adding RHF and lower Al2O3 enhanced the studied samples' radiation shielding properties. The results show that the TZNERHF glass sample has the highest mechanical properties. Thus, the TZNERHF sample is better than the other glass samples.
