Abstract

Toward the radiation shielding applications, this study produced and tested nanocomposite materials from the attapulgite clay, biochar, and nano-nickel combination at varied concentrations of X = 15.0 %, 30.0 %, and 45.0 %, for the abbreviation A₄₀B_XNi_(60-X). Fourier transform infrared (FT-IR), X-ray fluorescence (XRF), and Raman microscopy described pristine Attapulgite, biochar, and nano-nickel. In the photon energy range of 0.015: 15 MeV, their radiation shielding properties were determined using Monte-Carlo simulation code (MCNP) and Phy-X web software. Both of biochar, and nano-nickel increases the gamma and neutron radiation shielding in Attapulgite. The synthetic sample A₄₀B₁₅Ni₄₅ with significant nano-nickel doping has the maximum linear attenuation. On the other hand, the A₄₀B₁₅Ni₄₅ Nano nanocomposite which contain the high content of biochar, was found the highest against the fast neutrons. The synthesized A₄₀B_XNi_(60-X) nano-composites presents the best gamma and fast neutron radiation shielding capability to be used in the various radiation applications.

凹凸棒石clays@biochars@氧化镍作为一种具有优异辐射屏蔽特性的可持续纳米复合材料的研究

在辐射屏蔽应用方面，本研究以凹凸棒土粘土、生物炭和纳米镍为原料，在不同浓度X = 15.0%、30.0%和45.0%的条件下制备并测试了纳米复合材料A40BXNi（60-X）。傅里叶变换红外（FT-IR）、x射线荧光（XRF）和拉曼显微镜描述了原始凹凸棒石、生物炭和纳米镍。在光子能量为0.015:15 MeV的范围内，利用蒙特卡罗模拟代码（MCNP）和Phy-X web软件测定了它们的辐射屏蔽性能。生物炭和纳米镍都增加了凹凸棒石的γ和中子辐射屏蔽。纳米镍掺杂显著的合成样品A40B15Ni45线性衰减最大。另一方面，生物炭含量高的A40B15Ni45纳米复合材料对快中子的抑制效果最好。合成的A40BXNi（60-X）纳米复合材料具有良好的γ和快中子辐射屏蔽性能，可用于各种辐射应用。

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.
