Application of Nuclear Quadrupole Resonance to Detection of Explosives and Research Activities at CIAE
نویسندگان
چکیده
The detection of explosives is a challenging topic. The nitrogen-14 nuclear quadrupole resonance technique exploits the transitions between the energy levels split by the quadrupole interaction to detect the presence of explosives. It is a very promising new technique owing to its unambiguous detection and identification of explosives with low false alarm, high sensitivity and fast detection. The explosive screening machines based on the nitrogen-14 nuclear quadrupole resonance have been used for aviation security at airports. This paper describes the principle and application of nitrogen14 nuclear quadrupole resonance to detection of explosives and reviews the research activities in this domain at China Institute of Atomic Energy.

Nuclear Quadrupole Resonance (paper Ii)
The Polymer Diagnostics Section (Code 6122) of the U.S. Naval Research Laboratory (NRL) has expertise in solid state nuclear magnetic resonance (NMR), magnetic resonance imaging (MRI), and nuclear quadrupole resonance (NQR). In 1983, NRL established an interagency agreement with the Federal Aviation Administration (FAA) to advise the FAA on NMR methods to detect explosives. We were aware of ear...
متن کاملNQR-Based Explosives Detection—An Overview
Nuclear quadrupole resonance (NQR) is a radio frequency spectroscopic technique that can be used to detect solidstate compounds containing quadrupolar nuclei, a requirement fulfilled by most high explosives (and narcotics). In this paper, we present an overview of recent research in the detection of explosives using this technique. We also present mathematical models for the data for different ...

Nuclear Quadrupole Resonance (NQR) is effective for the detection and identification of certain types of explosives such as RDX, PETN and TNT. In explosive detection, the NQR response of certain 14N nuclei present in the crystalline material is probed. The 14N nuclei possess a nuclear quadrupole moment which in the presence of an electric field gradient produces an energy level splitting which ...

In this poin...
متن کاملRemote sensing by nuclear quadrupole resonance
Detection of explosives has the flavor of those mathematical problems that are not invertible. It is easier to hide explosives than to find them. Many approaches have been proposed and executed for the remote detection of explosives, contraband materials, weapons of mass destruction, currency, etc. Most detection technologies suffer from a common problem: the features they look for, such as dis...
