We designed a set of non-destructive system which is based on ray inspection systems, it mainly used to detect the Green Channel Cargo, and the result will be given out within 30 seconds. The ray coefficient of the Green Channel Cargo are different from the other transport cargo, so we can measure the absorption coefficient and compare it with the standard samples which is pre-built. The moved radioactive source and detector are designed, in order to prevent the mixed goods, we designed the removable radioactive sources and detectors, so the goods can be scanned up and down and around. Once the goods are mixed together, the ray coefficient which is calculated synchronously will be abnormal, parking and manual inspection is a supplementary means, so as to achieve a low-cost non-destructive testing.
