A relocatable container inspection device, which is constituted by modularized units, is used for inspecting a container. The device comprises: a first cabin unit including a radiation source for generating a beam of penetration radiation for penetrating the container to be inspected; a second cabin unit including detectors for detecting the beam of penetration radiation penetrating through the container being inspected and producing corresponding radiographic signals, the second cabin unit and the first cabin unit being arranged oppositely in both sides of an inspection passage; a gantry unit bridging the first cabin unit and the second cabin unit to form a portal-shaped frame adapted for straddling the container being inspected; means for moving the frame relative to the container being inspected along the inspection passage, so that the detectors receive the beam of the penetration radiation generated from the radiation resource and passing through the container being inspected, thereby continuously scanning the container and producing the corresponding radiographic signals, wherein the first cabin unit, the second cabin unit and the gantry unit are all individually made as modular units so as to be quickly and easily assembled and disassembled with each other on the inspection site. In the present invention, all of the modularized units of the container inspection device can be easily assembled and disassembled in the work field, and the dimensions of each modular unit are sized to be suitable for road transports and to be facilitate for the device's movement.
摘要:
The present invention discloses a method for inspecting an object using multi-energy radiations and an apparatus thereof. The method comprises the steps of: causing multi-energy radiations to interact with an object under inspection; detecting and recording detection values after an interaction between the multi-energy radiations and the object under inspection; substituting a portion of the detection values into a predetermined calibration function to obtain information comprising primary material attribute; and determining further material attributes of the object by applying a set of functions suitable for a energy band corresponding to the information. The present invention is applicable to the large container cargo inspection without opening containers at customs, ports and airports.

摘要:
For quarantine treatment of a farming and forestry product for pest control, a method and a device may irradiate logs as a phytosanitary treatment with electron beams. The method may include: spreading the logs; aligning the spread logs to be flush at one end; conveying the spread and flush logs laterally; conveying the logs longitudinally through an irradiation field formed by accelerators to provide treatment of irradiation with the electron beams; throwing the irradiated logs out; and laterally conveying the logs away. The device may include a conveying device for conveying the logs, a shielding structure surrounding the conveying device, and accelerators provided in the conveying path of the conveying device. Two or more accelerators may be provided in centrosymmetry about the conveying path.
