A device for intermittently jetting gas includes a gas source, a gas conduit with one end being communicated with the gas source and the other end being in communication with a nozzle, a rotary disc and a motor, the disc being mounted on a rotating shaft of the motor for rotating along with the shaft, wherein the rotary disc is provided with at least one opening through which a gas in the gas conduit is jetted when the opening is aligned with the outlet of the gas conduit. The device can freely adjust the gas jetting frequency by adjusting the rotation speed of the motor, and thus increase the gas jetting frequency and effectively flow off the suspicious particles carried in the human clothes.

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.
