Abstract

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

{L A C}_{A W} < {L A C}_{A W - 10 S i} < {L A C}_{A W - 10 T i} < {L A C}_{A W - 10 F e}

. 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.

含 SiO2、Fe2O3 和 TiO2 的磷灰石-硅灰石的伽马吸收和辐射屏蔽特性

本研究介绍了在按重量计掺杂了 10%二氧化硅（AW-10Si）、氧化铁（AW-10Fe）和二氧化钛（AW-10Ti）的 SiO2-CaO-Al2O3-MgO-P2O5-CaF2 玻璃（AW）中具有磷灰石-硅灰石（AW）晶体结构的玻璃陶瓷的伽马相互作用参数。玻璃陶瓷的密度是根据阿基米德法测定的，而玻璃的质量衰减系数（MAC）则是使用 PHITS 模拟代码对 15 keV-15MeV 能量范围内的伽马光子进行估算的。AW、AW-10Si、AW-10Ti 和 AW-10Fe 的密度分别为 2.90、2.92、2.91 和 3.05 g/cm3。玻璃的线性衰减系数依次为 LACAW<LACAW-10Si<LACAW-10Ti<LACAW-10Fe。金属氧化物的加入提高了 AW 的衰减系数。随着玻璃密度的降低，HVLs 逐渐增加。在所研究的玻璃中，AW-10Fe 的光子吸收和散射相互作用截面最好。这项研究表明，与一些商业和最新研究的屏蔽玻璃相比，AW-x 玻璃是无毒、便宜、环保和有效的屏蔽玻璃。

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.
