摘要

采用熔融淬火工艺制备了医药玻璃废料（PGW）基玻璃体系（PG玻璃体系），其组成为（70-x）PGW: 20Na2O: 10ZnO: xBaO（其中x = 0、5、10、15、20和25 mol%）。对PG玻璃体系的物理光学性质（如密度和折射率）的测量发现，随着BaO含量的增加，密度和折射率均有所增加。x射线衍射（XRD）证实了该材料的非晶结构，无尖峰。从质量衰减系数（MAC）和半值层（HVL）两个方面研究和分析了X射线和伽马射线的屏蔽性能。此外，还将伽玛射线的实验结果与FLUKA蒙特卡罗进行了比较。此外，还比较了不同材料对X射线和γ射线的屏蔽特性。结果表明，BaO含量的增加提高了材料对X射线和γ射线的屏蔽性能。此外，还对热中子的屏蔽性能进行了解释。这项工作的结果表明回收制药玻璃废料用于屏蔽X射线和伽马射线以及热中子的潜力。

Innovative technologies of waste pharmaceutical recycling for radiation shielding glass production

The pharmaceutical glass waste (PGW) based glass systems (PG glass systems) were fabricated for ionizing radiation shielding glass in compositions (70-x)PGW: 20Na2O: 10ZnO: xBaO (where x = 0, 5, 10, 15, 20 and 25 mol%) using melt quenching process. The physical and optical properties measurement of PG glass systems such as density and refractive index found that both values increased with increasing BaO content. The X-rays diffraction (XRD) process confirmed the non-crystalline structure with no sharp peaks. The X and gamma-rays shielding properties have been investigated and analyzed regarding the mass attenuation coefficient (MAC) and half value layer (HVL). Moreover, the experimental results for gamma-rays were compared with FLUKA Monte Carlo. Additionally, X and gamma-rays shielding characteristics were compared with some materials. It was found that the increasing BaO content improved X and gamma-rays shielding properties. Moreover, the thermal neutrons were also explained on shielding properties. The results of this work indicate the potential of recycling pharmaceutical glass waste for shielding X and gamma-rays, as well as thermal neutrons 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.
