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.
