Vehicle-mounted radiation detection system

Abstract

A vehicle-mounted radiation inspection system comprising a travelling vehicle body (202 and 203), a probing arm (202 and 203), a radiation source (206), and a detector (204). The vehicle-mounted radiation inspection system also comprises a follower mechanism (100) that is separated from the probing arm (202 and 203). The follower mechanism (100) comprises a radiation-shielding material, and, when inspecting a to-be-inspected object, the follower mechanism (100) follows and moves with the probing arm (202 and 203) in a non-contact manner, thus preventing radiation leakage. The inspection system obviates the need for filling high-density radiation-shielding materials such as lead into the probing arm (202 and 203), therefore allows for effective reduction of the weight of the probing arm (202 and 203), thus obviating the need to arrange of a counterweight on the travelling vehicle body (201) of the probing arm (202 and 203), therefore allowing for effective solution of the problem of excessive mass of the vehicle-mounted radiation inspective system. While at the same time, this allows for precision control of the travelling process of the follower mechanism (100), and for prevention of collision between the follower mechanism (100) and an active mechanism.

Description

technical field [0001] The invention relates to the technical field of radiation detection, in particular to a vehicle-mounted radiation detection system. Background technique [0002] In the prior art, the vehicle-mounted container / vehicle inspection system is one of the large container / vehicle inspection systems, capable of organic / inorganic material identification, rapid scanning and radioactivity monitoring, and its core technology is radiation imaging technology, which converts radiation into The source and the retractable detector arm are mounted on the chassis of the commercial vehicle. When the inspection is performed, the detector arm is extended to form a scanning channel. The scanned vehicle directly drives into and passes through the scanning channel. The radiation source generates rays, passes through the scanned vehicle, and the detector arm receives the rays to form a scanning image. Due to the need for radiation protection, the detector arm must be filled wi...

Problems solved by technology

The problem with this technology implementation is that the mass of the detector arm end is relatively large, which doubles the mass of the detector arm control end. In order to ensure the balance of the commercial vehicle chassis equipped with the detector arm, a balance must be set on the commercial vehicle chassis. The counterweight used increases the quality and cost of the entire equipment, damages the flexibility of the entire equipment, and is not conducive to the rapid transition of the vehicle-mounted container / vehicle inspection system
