Abstract
The neodymium oxide product was separated from Gibbsite natural ore by an ion exchange process. Nd2O3 was doped in a glass system using a melt-quenching technique with the formula 55B2O3–15SiO2-(30-x)Na2CO3-xNd2O3 where x varied from 0 to 0.5 mol%. The amorphous structure of the glass system is ensured using X-ray analysis and the surface morphology is described using a scanning electron microscope and infrared spectroscopy. The Monte Carlo simulation method and the theoretical calculation were applied to estimate the role of Nd2O3 concentration on the radiation shielding properties of the prepared glass samples. The increase in the Nd2O3 content increases the linear attenuation coefficient and radiation protection efficiency while the half-value thickness decreases. The linear attenuation coefficient increased between 0.187 and 0.191 cm−1 at 0.662 MeV, while the half-value thickness decreased between 3.698 and 3.628 cm. The addition of Nd2O3 enhances the radiation shielding properties of the prepared glass samples.
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.
