DUAL-MODE RAPIDLY-PASSING TYPE MOVING TARGET RADIATION INSPECTION SYSTEM AND METHOD

摘要

A dual-mode rapidly-passing type moving target radiation inspection system comprises a radiation source, a collimator (220), sensor units (110, 121, 122, 150, 160), a control module (500), a radiation detector and a radiation imaging device, wherein the sensor units (110, 121, 122, 150, 160) 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 (500) 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.
