Gamma absorption and radiation shielding properties of apatite-wollastonite containing SiO2, Fe2O3, and TiO2
This research presents the gamma interaction parameters of glass-ceramics with the apatite-wollastonite (AW) crystal structure within the SiO2–CaO–Al2O3–MgO–P2O5–CaF2 glass (AW) doped with 10% SiO2 (AW-10Si), Fe2O3 (AW-10Fe), and TiO2 (AW-10Ti) by weight. The density of the glass ceramics was determined based on the Archimedes method while the mass attenuation coefficients (MACs) of the glasses were estimated using the PHITS simulation code for gamma photons within the 15 keV-15MeV energies. The obtained densities of AW, AW-10Si, AW-10Ti, and AW-10Fe are 2.90, 2.92, 2.91, and 3.05 g/cm3, respectively. The linear attenuation coefficients of the glasses followed the order . The addition of the metal oxides improves the attenuation coefficients of AW. A gradual increase in the HVLs was observed as the glass density decreased. AW-10Fe has the best photon absorption and scattering interaction cross-sections among the investigated glasses. This study showed that AW-x glasses are nontoxic, cheaper, environmentally friendly, and effective shields compared to some commercial and recently researched shielding glasses.
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.
