Description

technical field [0001] The invention relates to a small backscattered X-ray inspection device, which belongs to the technical fields of X-ray safety inspection and radiation imaging. technical background [0002] X-ray backscattering technology is mainly used in the detection of security inspections, hidden drugs and explosives. X-ray backscattering technology can distinguish different types of substances, especially explosives and drugs mixed in multiple types of items or hidden in camouflage interlayers. All kinds of contraband that empties the structural space, especially effective for the detection of sheet explosives. The backscatter detector and the X-ray source are on the same side of the object to be inspected. It does not require whether the rays can penetrate the object to be inspected. As long as the energy of the rays can meet a certain intensity requirement, the thickness of the inspection can be large enough; backscattering technology can It is used for non-co...
