摘要

在本研究中，我们采用自行研制的紧凑型D-D中子发生器，设计了一个中子辐射生物装置。研究结果表明，铅是中子渗透率最好的材料;因此，我们选择硬铅作为该装置的结构材料。我们的研究揭示了一个与传统观点不同的现象，即从设备顶部的硬铅材料反射的中子的剂量贡献大约是聚乙烯材料的两倍。因此，本装置顶部反射镜的材料也选用了硬铅。研究还表明，该装置具有良好的剂量均匀性，根据模拟结果可以得到各照射区的标准中子吸收剂量。该装置可进一步促进中子辐射生物效应和突变育种等未来研究工作的发展。关键词:D-D中子发生器中子辐射生物装置吸收剂量免责声明作为对作者和研究人员的服务，我们提供此版本的已接受稿件(AM)。在最终出版版本记录(VoR)之前，将对该手稿进行编辑、排版和审查。在制作和印前，可能会发现可能影响内容的错误，所有适用于期刊的法律免责声明也与这些版本有关。国家自然科学基金项目(No. 12075106)、甘肃省自然科学基金项目(No. 20JR10RA607)和中央高校基本科研业务费专项资助。披露声明作者未报告潜在的利益冲突。本研究由中央高校基本科研业务费资助;国家自然科学基金[12075106];甘肃省自然科学基金项目[20JR10RA607]。

Research on the design of a radiation biodevice based on a compact D-D neutron generator

ABSTRACTIn this research, we used a self-developed compact D-D neutron generator and designed a neutron radiation biological device. The research results showed that lead was the material with the best neutron permeability; thus, hard lead was selected as the structural material for this device. Our research disclosed a phenomenon that differed from conventional wisdom, namely, the dose contribution of the neutrons reflected from the hard lead material at the top of the device was about twice that of the polyethylene material. Therefore, hard lead was also selected for the material of the top reflector in this device. The study also showed that the device had good dose uniformity, and the standard neutron absorption dose in each irradiation zone could be obtained according to the simulation results. This device may further promote the development of future research work such as neutron radiation biological effects and mutation breeding.KEYWORDS: D-D neutron generatorNeutronRadiation biodeviceAbsorption doseDisclaimerAs a service to authors and researchers we are providing this version of an accepted manuscript (AM).
