Effects of Er2O3 doping on the physical properties and gamma/neutron shielding performance of borate-tellurite glasses: PHITS Monte Carlo simulations
Presently, there have been consistent research towards designing and testing of novel materials with high radiation shielding potential. This present study investigates the effects of Erbium oxide (Er2O3) doping on the physical and radiation shielding features of mixed telluro-borate glasses containing B2O3–TeO2–PbO–BaO–Bi2O3-xEr2O3, (with x = 0.5, 1.0 and 2.0 mol %). The produced glasses (BTE0.5, BTE1 and BTE2) were studied for their physical and radiation shielding properties. The results showed that the density of the glasses increased from 3.97 to 4.25 g/cm3, while molar volume decreased from 4.25 to 3.95 cm3/mol at increasing Er2O3 addition from 0.5 to 2.0 mol %. The measured mass attenuation coefficient (MAC) validated by XCOM and PHITS (with no significant difference between the two validated data) showed that MAC values generally increased from BTE0.5 to BTE2 at all energy levels between 0.015 and 15 MeV. This suggest that increasing Er2O3 in the BTE composition enhanced shielding effectiveness. Sample BTE2 exhibited lowest half-value layer (HVL) followed by BTE1 and BTE0.5 at lower energies, which indicates that increasing Er2O3 content improves shielding efficiency at low energies. However, at increased photon energies, the differences in the samples decline, suggesting that all the samples (BTE0.5, BTE1 and BTE2) are likewise effective for high-energy radiation shielding. The fast neutron removal cross-section (ΣR) also improves at increasing Er2O3 content with values ranged from 0.10235, 0.10374, and 10672 cm−1 for BTE0.5, BTE1, and BTE2, respectively. In the overall, sample BTE containing higher Er2O3 content (BTE2) showed promising properties comparable with other shielding materials highlighting its potential for gamma/neutron shielding applications.
期刊介绍:
Radiation Physics and Chemistry is a multidisciplinary journal that provides a medium for publication of substantial and original papers, reviews, and short communications which focus on research and developments involving ionizing radiation in radiation physics, radiation chemistry and radiation processing.
The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. This could include papers that are very similar to previous publications, only with changed target substrates, employed materials, analyzed sites and experimental methods, report results without presenting new insights and/or hypothesis testing, or do not focus on the radiation effects.
