Abstract

This study examines the efficacy of rubber, a non-toxic hydrocarbon polymer, as a shielding material against gamma rays and neutrons. We analyse four types of rubbers: Neoprene, Butyl, Natural, and Silicone, using computational methods and Monte Carlo simulations via MCNP (version 6.3) to evaluate their gamma ray and neutron shielding parameters. Notably, Neoprene, enhanced with chlorine, shows superior gamma ray attenuation capabilities with a mass attenuation coefficient (MAC) of 760.446 cm²/g at 0.015 MeV, indicating its potential as an effective material for gamma ray shielding applications. Conversely, Butyl rubber, with its high hydrogen content, exhibits exceptional neutron attenuation properties, with the highest Σ_R value of 11.861 1/cm, making it a preferred choice for neutron shielding. This investigation underscores the versatility and environmental benefits of rubber materials in radiation protection, highlighting their potential as lightweight, customisable and sustainable alternatives to conventional shielding substances like lead. Our findings reveal prominent advantages of Neoprene for gamma ray shielding and Butyl rubber for neutron protection, contributing to the development of safer, more effective radiation protection solutions.

不同橡胶材料的基准分析：为航空航天和电子应用定制轻质、有效的辐射防护解决方案

本研究探讨了橡胶（一种无毒碳氢化合物聚合物）作为伽马射线和中子屏蔽材料的功效。我们分析了四种橡胶：我们分析了四种橡胶：氯丁橡胶、丁基橡胶、天然橡胶和硅橡胶，通过 MCNP（6.3 版）使用计算方法和蒙特卡罗模拟来评估它们的伽马射线和中子屏蔽参数。值得注意的是，氯增强氯丁橡胶显示出卓越的伽马射线衰减能力，在 0.015 MeV 时的质量衰减系数（MAC）为 760.446 cm2/g，这表明它有潜力成为伽马射线屏蔽应用的有效材料。相反，含氢量较高的丁基橡胶具有优异的中子衰减特性，ΣR 值最高，为 11.861 1/cm，因此成为中子屏蔽的首选材料。这项研究强调了橡胶材料在辐射防护方面的多功能性和环境效益，突出了它们作为轻质、可定制和可持续的传统屏蔽物质（如铅）替代品的潜力。我们的研究结果揭示了氯丁橡胶在伽马射线屏蔽和丁基橡胶在中子防护方面的突出优势，有助于开发更安全、更有效的辐射防护解决方案。

期刊介绍： The Journal of Rubber Research is devoted to both natural and synthetic rubbers, as well as to related disciplines. The scope of the journal encompasses all aspects of rubber from the core disciplines of biology, physics and chemistry, as well as economics. As a specialised field, rubber science includes within its niche a vast potential of innovative and value-added research areas yet to be explored. This peer reviewed publication focuses on the results of active experimental research and authoritative reviews on all aspects of rubber science. The Journal of Rubber Research welcomes research on: the upstream, including crop management, crop improvement and protection, and biotechnology; the midstream, including processing and effluent management; the downstream, including rubber engineering and product design, advanced rubber technology, latex science and technology, and chemistry and materials exploratory; economics, including the economics of rubber production, consumption, and market analysis. The Journal of Rubber Research serves to build a collective knowledge base while communicating information and validating the quality of research within the discipline, and bringing together work from experts in rubber science and related disciplines. Scientists in both academia and industry involved in researching and working with all aspects of rubber will find this journal to be both source of information and a gateway for their own publications.
