The radiation inspection system according to claim 9, wherein the radiation shielding structure comprises a shielding box provided with a plurality of shielding doors corresponding to the plurality of radiation inspection channels (2), the radiation source (1) is provided in the shielding box, and a radiation shielding state of the radiation shielding structure is switched by opening or closing of each shielding door.
11. A radiation inspection method employing the radiation inspection system of any one of claims 1 to 10, comprising: -simultaneously radiation inspecting an object (4) located in a plurality of radiation inspection channels (2) with the radiation source (1) and the detection device (3), the radiation inspection method further comprising: after the radiation source (1) and the detection device (3) perform radiation inspection on the inspected object (4) in the plurality of radiation inspection channels (2) at the same time, judging whether the inspected object (4) needs to be inspected again, and if so, conveying the inspected object (4) into another radiation inspection channel (2) for radiation inspection so as to perform radiation inspection on the inspected object at different angles.
12. The radiation inspection method of claim 11, wherein the radiation inspection method further comprises: before the radiation source (1) and the detection device (3) simultaneously perform radiation inspection on the objects (4) positioned in a plurality of radiation inspection channels (2), conveying the objects (4) from the area to be inspected into the radiation inspection channels (2) by using first end conveying equipment; and/or after radiation inspection of the inspected object (4) located in the plurality of radiation inspection channels (2) by the radiation source (1) and the detection device (3), receiving the inspected object (4) from the radiation inspection channels (2) and conveying the inspected object (4) to a region to be taken by using a second end conveying device.
13. The radiation inspection method as claimed in claim 11, characterized in that the radiation inspection system further comprises adjusting the exit angle of the radiation source (1) to control whether each of the radiation inspection channels (2) is involved in a radiation inspection.
