Movable IDCs with an energy of 6 MeV allow the decision on the conformity of the cargo to be declared in the shipping documents based on the x-ray image obtained. These complexes are used at automobile checkpoints and provide a throughput of up to 20 trucks per hour. The technological equipment of the complex is located in a quick-erected structure or a structure made of prefabricated concrete modules with simplified radiation protection. The X-ray unit and the detection system are mounted on a frame that can automatically move along rails. During the scan, the inspected vehicles are stationary.
