摘要

In this work, we carry out a theoretical investigation of the radiation-shielding characteristics of the 10Li2O-90GeO2 and 10Bi2O3-90GeO2 glass systems—hereafter—LiOGe and BiOGe, respectively. For this purpose, the MCNPX code and Phy-X software are used, with photon energies ranging from 0.015 to 15 MeV. The investigation includes the determination of effective atomic number (Zeff), tenth-value layer (TVL), mass attenuation coefficient (MAC), mean free path (MFP), and half-value layer (HVL). The results show a relative difference of only 5% between the data obtained from Phy-X and MCNPX. The computed mass attenuation coefficient (MAC) values for LiOGe decrease from 48.109 to 0.028 cm2/g, and for BiOGe from 92.604 to 0.036 cm2/g, as photon energy increases from 0.015 to 15 MeV. The linear attenuation coefficient (LAC) for LiOGe decreases from 190.510 to 0.112 cm−1, and for BiOGe from 440.797 to 0.171 cm−1, over the same energy range. The new systems appear more promising for shielding applications when compared with those documented in the literature. Furthermore, compared to LiOGe, the results indicate that BiOGe is a superior glass system for attenuating gamma and X-ray photons over the whole energy range of 0.015 to 15 MeV. BiOGe is better for shielding since it has greater MAC, LAC, and Zeff values and lower HVL, TVL, and MFP values. The comparison of the radiation-shielding properties of the studied glasses with those of other reported glasses suggests that the present glasses are more promising than the previously reported glasses for radiation shielding.
