Classification of explosive detection methods
- Explosives detection technology in the world is mainly divided into two categories: volume detection technology and trace detection technology. Among them, block detection technology can be divided into imaging detection technology and nuclear detection technology; according to the state of the sampling target, trace detection technology can be divided into steam detection technology and particle detection technology [2] .
The mainstream method of explosives detection
- At present, the mainstream methods of explosive detection worldwide include metal detector methods (mainly used for landmine detection), neutron detection methods, X and -ray detection methods, electromagnetic measurement methods, nuclear quadrupole method, and molecular particle analysis methods. , Electrochemical detection method, laser detection method, terahertz method, etc. [3] .
- Among them, X or -ray method, neutron method, electromagnetic measurement method, etc. have certain limitations in practical applications, that is, X-ray can only detect the density and effective atomic number of an object, and cannot distinguish its chemical composition. Application of neutron detection The radiation protection required is relatively difficult, and electromagnetic methods may cause damage to magnetic recording media and magnetic materials. Industry and academia have never stopped exploring new types of explosives detection technology and devices.
Explosives detection applications
- With the great anxiety and panic brought to the public by terrorist attacks worldwide, explosive detection has become a question that countries attach great importance to, and the timely and effective detection of hidden explosives has become an urgent task for the international community. Currently, It has been widely used in customs, aviation, subway, station, prison and other departments [4] .
