摘要
在临近空间辐射环境的诸多因素中,中子对飞行器的安全、可靠运行以及人员健康的威胁最为严重。文章介绍了临近空间中子的来源及其对飞行器和人体的危害,指出临近空间中子探测研究的重要意义,简要阐述了临近空间中子探测的原理与方法,最后探讨了临近空间中子探测领域所涉及的几个关键问题。
Among many kinds of particles that constituting near space radiation environment, neutron is the most threatening one to the vehicle＇s safe, reliable operation and the human health. This paper firstly introduced the neutron sources in near space, described the harm to the aircraft and human body that caused by neutron, pointed out the importance of research on neutron detection in near space, then discussed briefly the principles and methods of neutron detection in near space, and finally focused on several key issues involved in the near space neutron detection area.
