A promising alternative: examining TVS tellurite glass for gamma radiation shielding applications

Radiation shielding is crucial in many types of medical, industrial, and nuclear
facilities due to the widespread usage of radioactive isotopes. In this research, we
examine the impact of tellurite 65TeO2–(35-x)V2O5-xSm2O3 glasses, where x
ranges from 0.1 to 5mol%, for its nuclear security and radiation shielding versus
gamma attenuation capabilities. For gamma, the effect that the systematic
replacement of Sm2O3 with V2O5 has on the shielding qualities was dissected
in great depth. In addition, comparative research was carried out using the most
recent borate glasses and the typical shielding materials considered the industry
standard. In this study, we utilized the FLUKA algorithm and the FLAIR graphical
interface to calculate the attenuation coefficients of glass compositions in the
65TeO2–(35-x)V2O5-xSm2O3system. The gamma energies of 0.356, 0.662, 1.332,
and 2.614 MeV, commonlyusedingammashieldinginvestigations, were selected
as the radiation source. A comparison between the simulation results by FLUKA
and theoretical calculations for mass attenuation coefficients demonstrated
excellent agreement, confirming the reliability and accuracy of the FLUKA
simulation method. The findings of the current research point to the fact that
the TVS5 sample has the highest GMAC and lowest GHVL and GMFP, among other
glasses. This points to the possibility that the TVS5 sample might be used in
radiation shielding activities, which would result in increased nuclear safety
