摘要： A dual-mode rapidly-passing type moving target radiation inspection system comprises a radiation source, a collimator, sensor units, a control module, a radiation detector and a radiation imaging device, wherein the sensor units are used for identifying the type of a moving target and monitoring the position of the moving target in an inspection channel; the control module is used for controlling the radiation source to emit rays in a preset working mode on the basis of the type and the position of the moving target; the preset working mode corresponds to the type of the moving target, and the rays emitted by the radiation source in different working modes differ in dosage rate. Also disclosed is a dual-mode rapidly-passing type moving target radiation inspection method. The inspection system and method described above are capable of radiation inspection of the entire moving targets such as vehicles.

摘要： A flying spot forming apparatus includes a radiation source and a shielding body. A side wall of the shielding body is provided with at least two pairs of helical grooves. Each helical groove is provided with a predetermined slope. A first incident groove is adjacent to a second incident groove. A head end of the first incident groove is higher than a head end of the second incident groove. A tail end of the first incident groove is higher than a tail end of the second incident groove. The tail end of the first incident groove is not higher than the head end of the second incident groove. A first axial cross section of the shielding body intersects with the tail end of the first incident groove. A second axial cross section intersects with the head end of the second incident groove.

摘要： A system and method for radiation inspection on a moving object. The system comprises a radiation source and a radiation detector. Rays emitted by the radiation source are limited in a scanning area. The scanning area is provided by a first boundary surface and a second boundary surface. The system also comprises: multiple detection units arranged along a detection channel in turn and used for triggering and sending a signal when detecting that the moving object arrives or leaves; and a control module used for receiving signals sent by the multiple detection units and controlling the radiation source according to the received signal. The first to third detection units among the multiple detection units are located at one side of the scanning area and near the first boundary surface. The fourth to sixth detection units among the multiple detection units are located at the other side of the scanning area and near the second boundary surface. The system and the method can implement radiation inspection on moving objects traveling in multiple directions.
