Materials Map under construction

The Materials Map is still under development. In its current state, it is only based on one single data source and, thus, incomplete and contains duplicates. We are working on incorporating new open data sources like ORCID to improve the quality and the timeliness of our data. We will update Materials Map as soon as possible and kindly ask for your patience.

Abstract

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 65TeO 2 –(35-x)V 2 O 5 -xSm 2 O 3 glasses, where x ranges from 0.1 to 5 mol%, for its nuclear security and radiation shielding versus gamma attenuation capabilities. For gamma, the effect that the systematic replacement of Sm 2 O 3 with V 2 O 5 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 65TeO 2 –(35-x)V 2 O 5 -xSm 2 O 3 system. The gamma energies of 0.356, 0.662, 1.332, and 2.614 MeV, commonly used in gamma shielding investigations, 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 G MAC and lowest G HVL and G MFP, 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.
