Worldwide, terrorists use hidden explosives for cheats, hijackings, horrific and tragic events such as machine crashes and train explosions. In order to eliminate the occurrence of these tragic events and ensure the safety of people's lives and property, airports, docks, railway stations and other places must be able to effectively detect hidden explosives in luggage and parcels. Therefore, the detection of hidden explosives is a concern of the world.
At present, many countries in the world are studying explosive detection instruments of various methods. Conventional X-ray imaging technology mostly detects the density of luggage and parcels. It is up to the operator to judge based on experience and cannot tell with certainty whether the baggage and the package contain explosives.
The China Institute of Atomic Energy, in cooperation with the Beijing Municipal Public Security Bureau, uses the Nuclear Quadrupole Resonance (NQR) technology to develop an explosives detection device that performs an inspection of explosives based on the NQR characteristics of each human being. The explosives detection device not only detects explosives, but also detects radioactive materials at the same time. The device is a channel structure with only a few buttons. At present, only a few countries in the world can produce practical detection devices.
China has developed a new explosive detector
A channel-type explosive detector for the inspection of luggage and suitcases successfully developed by the China Institute of Atomic Energy has recently passed the acceptance and review of relevant experts.
