Embodiment approach

[0016] see figure 1 , 2 , an air container / pallet cargo inspection system using an accelerator as a radiation source, mainly including an electron linear accelerator 1, a collimator 2, a horizontal detector arm 8, a vertical detector arm 7, and conveyed by a plate conveyor 10 and an upper roller. Machine 5, composite transmission device consisting of roller conveyor 12, radiation shielding wall 9, equipment cabin 14, and operating room 3. The accelerator 1, the collimator 2, and the vertical detector arm 7 are respectively installed on the accelerator base 15, the collimator base 18, and the vertical detector arm base 17. The collimator 2 is located between the conveying device and the accelerator 1 , the upper end of the collimator 2 supports a horizontal detector arm 8 , and the vertical detector arm 7 is installed on the other side of the conveying device opposite to the accelerator 1 . The horizontal detector arm 8 is located directly above the transmission device, and o...

Abstract

This invention relates to system for examining aviation container / tray cargoes, which comprises electronic linear accelerator, gas detector, a collimator, lateral detector beam, vertical detector beam, transfer device, radiation shielding wall, equipment module and a operation room in which the gas detectors are mounded on the said two beams separately which are on the same surface with the accelerator and collimator forming a stable portable frame with the two beams and the collimator is in between the accelerator and the transferring device which comprises a roller way and apron conveyers. The portal frame and transferring device make up the scan channel set with radiation module and operation room with a table inside.

Description

(1) Technical field: [0001] The invention relates to an automatic scanning radiation detection system for large objects, in particular suitable for air container / pallet inspection systems, and belongs to the technical field of radiation detection. (two) background technology: [0002] The air container / pallet cargo inspection system is one of the inspection equipments urgently needed by the customs. At present, the inspection of domestic and foreign aviation articles mainly adopts unpacking inspection or X-ray machine inspection. The unpacking inspection takes a long time, the daily inspection volume is low, and the inspection cost is high. Due to the low ray energy and poor penetrability of the X-ray machine, it mainly relies on reflection imaging, so the part of the image that can be seen clearly is limited to the objects within the range of 20-30 cm from the container wall on one side of the container. The image quality and scope of application It cannot meet the requir...
