Comparative analysis of TiO2, Fe2O3, CaO and CuO in borate based glasses for gamma ray shielding

Abstract

This research intends to utilize melt-quenching technique in order to examine the radiation shielding capability of 10 % Mo, 10 % Na2O, 20 % PbO, and 60 % B2O3 glass system, with varying CaO, TiO2, CuO, Fe2O3 or Mo. XCOM and MCNP simulations were utilized to analyze the radiation shielding properties of the fabricated glasses. The results revealed CuO having the superior MAC of 49.91 cm2/g, then Fe2O3 with 49.24 cm2/g, followed by CaO with 49.10 cm2/g, and TiO2 with 48.49 cm2/g as the least. CuO and Fe2O3 were confirmed to have least HVL compared to CaO and TiO2. The value of the lead equivalent thickness showed fluctuation against the gamma energy, where it raisess within the photoelectric region and falls after the photoelectric region. The data reveal that, the lead equivalent thickness at 0.1 MeV were 7.88 cm, 7.86 cm, 7.81 cm and 7.80 cm for TiO2, Fe2O3, CaO, and CuO in the same order, respectively. The transmission factor (TF) raises as the gamma energy raises, having TiO2 as the highest with 76.068 %, while the radiation protection efficiency dropped as the energy raises.
