Abstract

The invention relates to a backscatter and transmission combined safety detector of X rays, belonging to the technical field of social safety inspection and safeguard detection devices and non-destructive detection devices. The backscatter and transmission combined safety detector disclosed by the invention is mainly characterized in that a backscatter ray slit and a transmission ray bundle slit are arranged on a rotating cylinder, and the two slits respectively generate a flying-spot scanning ray bundle and a transmission ray bundle, so that the same X-ray source and the same ray bundle scanning generator can be used for simultaneously providing two kinds of ray image information of a detected object to comprehensively perform the detection and judgment and further increase the detection ratio. The backscatter and transmission combined safety detector of the X rays is characterized by simple structure, low cost and the like, and can be used for detection of bags and suitcases, scanning of the human body and safety detection on the aspects such as industry (flaw detection), military and the like.

Description

technical field [0001] The invention relates to an X-ray scanning safety detection device, in particular to a combined anti-(back) scattering and transmission safety detector, which belongs to the technical field of social safety inspection and safety prevention detection equipment and non-destructive detection equipment. Background technique [0002] Chinese patent document (Application No. 01120599) discloses "a non-destructive testing method and device for gamma backscatter imaging". The focus is too large. However, the collimator and radiation shielding can be designed compactly, and the slit rotating body forming the flying spot can also be very compact. However, the size of the rod beam (pencil beam) is still too large, which affects the resolution. Generally, the energy of the isotope γ-ray source is relatively high, and the rotating slit body is required to be made of a heavy material with a certain thickness. Manufacturing and operation will be difficult. Especia...
