摘要

研究了腰果壳灰（CSNSA）、椰子壳灰（CCNSA）、棕榈仁壳灰（PKNSA）、瓜壳灰（MHA）、稻壳灰（RHA）、花生壳灰（PNSA）、棕榈仁壳灰（DPNSA）等果壳灰和果壳灰在0.015 ~ 0.284 MeV能量范围内的屏蔽γ射线性能。收集样品，清洗，在室温下干燥，并在200°C下使用马弗炉烧成灰烬30分钟。灰烬的密度以样品的质量/体积计算。使用能量色散x射线荧光分析仪（ARL-QUANT'X-EDXRF）分析样品的氧化物成分，不确定度为1 - 2%，分辨率为40 keV。将氧化物组成和密度输入到Phy-X/PSD中，获得伽马射线屏蔽参数。结果表明，能量为0.015 MeV时，CCNSA样品的MAC值最高，为2001.23 cm2/g， LAC值为6100.99 cm−1，具有较好的屏蔽性能，而RHA样品的MAC值和LAC值最低，具有较低的屏蔽性能。这表明，在所有检测样品中，CCNSA具有较好的屏蔽特性。因此，鼓励研究人员将CCNSA纳入混凝土或玻璃样品中，并测试其对其屏蔽性能的影响，以提高可持续发展目标的实现。

Feasibility study on the possibility of utilizing e-nut shell ashes for gamma-radiation protection application

This study explored the gamma-ray shielding performance of various fruit-nut shells and husk ashes like cashew-nut shell ash (CSNSA), coconut shell ash (CCNSA), palm-kernel-nut shell ash (PKNSA), melon-husk ash (MHA), rice-husk ash (RHA), peanut shell ash (PNSA), and deleb-palm-nut shell ash (DPNSA) within the energy range of 0.015–0.284 MeV. The samples were gathered, washed, dried at room temperature, and burnt to ashes at 200 ^°C for 30 min using a muffle furnace. The ashes' densities were calculated as mass/volumes of the samples. The samples were analyzed for oxide composition using an energy dispersive X-ray fluorescence analyzer (ARL-QUANT'X-EDXRF) with 1–2 % uncertainty and 40 keV resolution. The oxide compositions and densities were inputted in Phy-X/PSD to obtain the gamma-ray shielding parameters. The results showed that sample CCNSA at the energy of 0.015 MeV displayed the highest MAC value of 2001.23 cm²/g and LAC value of 6100.99 cm⁻¹, representing high shielding performance, while sample RHA exhibited the least MAC and LAC values, confirming its low shielding performance. This indicated that, among all the examined samples, CCNSA is characterized with the superior shielding features. Therefore, researchers are encouraged to incorporate CCNSA into either concrete or glass samples and to test its effect on their shielding performance in order to improve achievement of the Sustainable Development Goals.

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.
