【摘要】 X射线快速安全检查系统是港口、物流中心、公路卡口等场所对大量进出集装箱货物进行快速安全检查的X射线类检查系统。国内某厂商研制的X射线快速安全检查系统,采用司机直接驾车通过检查通道的方式来实现对集装箱卡车货物的快速检查,本文介绍该系统的工作流程,分析正常工况下司机被系统误扫、人员闯入或藏匿于集装箱中的安全风险,以及设计基准事故下的安全风险。结果表明,该系统是安全可行的,关键人群司机以及意外闯入检查通道的人员所受剂量低于相关标准的要求,对人员健康无影响。更多还原

【Abstract】 The X-ray rapid safety inspection system is a system for rapid and safe inspection of large quantities of incoming and outgoing container cargo at ports, logistics centers, highway bayonets and other places. Such a system, developed by Nuctech, uses a means of driving truck directly through the inspection channel to realize rapid inspection. The workflow of this system is introduced. The risks for drivers being accidentally scanned under normal working conditions, and for personnel breaking into or hiding in containers, are examined. And the safety risks under design basis accidents are analyzed as well. The results show that the system is safe and acceptable. An average member of the critical group of drivers receives a dose less than the relevant standards, while the dose to any personnel breaking into the inspection channel is as low as 4 μSv, which has no health impact.更多还原
