    摘要： The present invention provides an X-ray backscattering safety inspection system, comprising: an X-ray source comprising a plurality of target spots each individually controllable to emit X-rays; collimators configured to be respectively passed through the X-ray emitted from the plurality of target spots and output N pencil-shaped X-ray beams, and the N pencil-shaped X-ray beams are irradiated onto N locations of an object to be inspected; and N detectors configured to respectively receive scattering signals from the corresponding locations of the object to be inspected, in which N is a positive integer that is great than or equal to 2. The system may achieve double scannings in one scanning operation, which not only increases scanning speed but also enhances backscattering signal for imaging.

    摘要： A method for patrol inspecting and locating a radioactive substance, comprising: providing a background radioactive intensity value of environment; collecting radioactive intensity values from a inspecting region by a detector at a plurality of sampling points on a patrol inspection route; calculating a radioactive intensity distribution in the inspecting region on basis of the collected radioactive intensity values and the background radioactive intensity value; and determining a position of the radioactive substance on basis of the radioactive intensity distribution. Furthermore, a device for patrol inspecting and locating a radioactive substance comprises: two or more detectors configured to collect radioactive intensity values from a inspecting region around a patrol inspection route, at each of a plurality of sampling points on the patrol inspection route; and a movable carrier configured to carry the detector and to move along the patrol inspection route to pass by the sampling points. The method and device can obtain the position and the radioactive intensity distribution of the radioactive substance within the inspecting region on basis of the multiple-point observation on the patrol inspection route.
