摘要
为了检测出接近本底的低活度放射性物质,并且满足国家标准GB/T24246-2009中对行人辐射监测系统的性能要求,本文设计了一种行人辐射监测系统,并对监测系统低放射性探测灵敏度测量原理进行了研究。本监测系统在本底稳定性满足要求的基础上,能够探测到接近本底的低活度放射性物质,为相关开发机构或安检部门开展类似问题研究提供了参考和借鉴。
In order to detect low activity radioactive substances close to background and meet the performance requirements of pedestrian radiation monitoring system in national standard GB/T 24246-2009,a pedestrian radiation monitoring system is designed in this paper, and the measurement principle of low activity detection sensitivity of monitoring system is studied.On the basis of satisfying the requirements of background stability, the monitoring system can detect low activity radioactive substances close to the background, which provides reference for related development institutions or security inspection departments to carry out similar research.
