New Inspection Systems Based on the Registration of the Backscattered X-rays

摘要

X-ray systems are used in a wide range of security applications: inspection of luggage and carry-on items, inspection of vehicles, personal inspection, inspection of unattended items, industrial safety (testing of castings, honeycomb structures). To acquire an image, such systems use X-ray radioscopy method, which requires two-sided access to the inspected object, which in some cases limits the application. The report focuses on the experience of developing of inspection systems on the basis of registration of the backscattered X-radiation, which enables image acquiring with one-way access to the object of control. A characteristic feature of the method is also a small radiation dose to the inspected object and low level of unused radiation. The systems of various design and function are considered: portable one for operational inspection of personal belongings and unattended items, stationary for personal inspection, mobile for vehicles inspection. There are discussed the technical data of the systems, their application results, the possibility of use in the field of industrial safety.
