Detection of Hidden Explosives by Nanosecond Neutron Analysis Technique
One of the most promising methods of detection of hidden explosives and other dangerous substances is the so-called, “neutron in, gamma out” technique. The main idea of this method consists in irradiation of suspicious object or volume with neutrons and measurement of secondary γ-radiation caused by interaction of neutrons with the material of the irradiated object. Different chemical elements produce different characteristic γ-radiation as a result of inelastic scattering or capture of neutrons. By decomposing measured γ-spectra into contributions from different chemical elements, one can obtain elemental composition of the explored object and thus determine whether it contains hazardous (e.g. explosive) material or not.
