Abstract: Embodiments of the present invention provide a trailed multiple-viewing-angle item inspection system and method of operating the same. The inspection system includes: a trailer vehicle, a radiation inspection device, a power supply device and a power grid connection device. The trailer vehicle is mounted with a power supply chamber within which a power supply device and a power grid connection device are mounted and an inspection chamber within which a radiation inspection device is mounted. The radiation inspection device includes: ray radiation source configured to emit X-rays from various positions, detectors, a body frame, a transfer device, a data and image process system and a display and operation device. The trailed multiple-viewing-angle item inspection system of the present invention can obtain a transmission image containing depth information of an item by its one pass through the device, and achieve a high-speed inspection, a good image quality and a high inspection efficiency of hazardous articles, and its flexibility and movability can meet requirements in various working conditions.

Abstract: A method and device for detecting radioactive sources is disclosed. In one aspect, an example method includes measuring, by a detector, a count rate curve of an inspection object while the inspection object moves through the detector. Pattern recognition is performed on the count rate curve. Whether there are radioactive sources in the inspection object is determined according to a result of the pattern recognition, and if there are radioactive sources in the inspection object, a type of the radioactive sources is determined.
