A comprehensive study on the effect of TeO2 on the radiation shielding properties of TeO2-B2O3-Bi2O3-LiF-SrCl2 glass system using Phy-X / PSD software

The present work deals with the detailed investigations on the radiation shielding features of TeO2-B2O3-Bi2O3-LiF-SrCl2 glass system. The recent software namely Phy-X/PSD has been used to report the change in the photons attenuation features of this glass system with increasing the content of TeO2 from 25 to 85 mol% between 347 keV and 2506 keV. The results show that replacing B2O3 with TeO2 causes the increase in the density of the glass from 3.66 to 5.91 g cm(-3) which lead to increase the linear attenuation factor (mu). The mu has a direct relationship with energy and has a highly large value at 0.347 MeV (between 0.550 and 0.896 cm(-1)). The maximum effective atomic number occurs at 0.347 MeV and equals to 17.75, 19.78, 21.94, 24.24, 26.68, 29.29 and 32.07 for the TeBBiLS1- TeBBiLS7 samples. Thereafter, Z(eff) decreases quickly down to 0.826 MeV, and becomes almost constant between 1.173 and 1.333 MeV and very slightly increases at 2.506 MeV. The tenth value layer results imply that increasing the weight percentage of Te0 2 in the glasses from 25 to 85 mol% can reduce the thickness needed to attenuate or block the photons. TeBBiLS1 has the maximum half value layer (HVL) and was found to be in the range of 3.034-4.823 cm and TeBBiLS7 sample has the lowest HVL. Also, the results revealed that as the density increased, the mean free path (MFP) gradually decreased, and the attenuation ability improves.
