Özet

In the present study, it is aimed to be produced glass materials for radiation shielding by adding different proportions (0.02, 0.04, 0.06, 0.08, 0.1, 0.15 and 0.2 mol%) of TeO2 to (79.5-x)SiO2-2.5Al(2)O(3)-5Na(2)O-13B(2)O(3)-xTeO(2) borosilicate glasses (BS). The BS-TeO2 glasses were prepared by melt quenching method using TeO2 and BS powders. The produced glasses' fundamental structural properties were investigated using XRD, UV-vis, and FT-IR spectroscopic techniques. XRD patterns of the all prepared glass samples exhibited amorphous structure. The number of energy transitions in the UV-vis spectrum increased depending on the concentration of TeO2 . Furthermore, produced glasses' physical and mechanical properties were evaluated by calculating the bond strength, packing density, bridged oxygen numbers, and molar oxygen volume. Also, the gamma-ray shielding parameters (mass attenuation coefficient, effective atomic number, electron density, mean free path, half-value layer, and radiation protection efficiency) of the glasses were measured at photon energies in the range of 53.16-661.62 keV using a U-LEGe detector with high resolution. The mass attenuation coefficients of BS-TeO2 glasses were calculated at the same energies by using the MCNP5 code. The obtained values were compared with XCOM data, and a very good agreement was achieved between MCNP5 and XCOM. These results showed that the sample containing 0.2 mol % TeO2 was the best photon attenuation ability among other samples.(C) 2022 Elsevier B.V. All rights reserved.
