Abstract
A security inspection door comprising a narcotic drug/explosive detecting subsystem, a radioactive substance detecting subsystem and a metal detecting subsystem which are provided in a tank body is disclosed, wherein electromagnetic radiation shields are respectively provided around the three detecting subsystems, so that they are isolated from one another and are not interfered with one another. The three detecting subsystems are combined together to form a novel security inspection door, so the narcotic drugs/the explosives, the radioactive substances and the dangerous metal articles can be detected at the same time. Further, electromagnetic radiation shields are respectively provided around the three detecting subsystems, so that the three detecting subsystems are isolated from one another and are not interfered with one another, and thus, the inspection reliability and the inspection accuracy are improved.
