摘要：
In this paper, we studied the gamma photon attenuation properties for different germanate glasses systems with composition Sb2O3-GeO2-SiO2-Al2O3, TeO2-WO3-GeO2, GeO2-TeO2/SiO2-PbO-CaO-Tm2O3 and B2O3-GeO2-Gd2O3-Eu2O3-GdF3-BaF2. The mass attenuation coefficients (mu/rho) for the selected germanate glasses were calculated at different energies (between 0.015 MeV and 15 MeV) using the MCNPX code. The calculated MCNPX mu/rho values then compared with the WinXCom data to check the accuracy in the results. The results showed that the Sb2O3 replacement by SiO2 causes a decrease in mu/rho for Sb2O3-GeO2-SiO2-Al2O3 glass system. Also, it is found that for TeO2-WO3-GeO2 glass system, mu/rho decreases as GeO2 content increases from 1 to 20 mol%. While for GeO2-TeO2/SiO2-PbO-CaO-Tm2O3 glass system, the results revealed that the glass samples contain TeO2 possess higher mu/rho values than the samples contain SiO2. For the B2O3-GeO2-Gd2O3-Eu2O3-GdF3-BaF2 glasses, we found that the mu/rho values decrease as BaF2 is increased from 0 to 15 mol%. Moreover, it is found that 5OSb-OGe for series 1, TWGO for series 2, 2G4T for series 3 and X = 0 for series 4 glass samples among the studied glasses have the highest effective atomic number values. On the basis of the results achieved, 50Sb-OGe, TWGO, 2G4T and X = 0 samples have the best radiation shielding characteristics among the selected glasses.
