摘要：Fast neutron resonance radiography (FNRR) is an imaging method that exploits the characteristic crosssection
structure of different isotopes in the energy-range En=1-10 MeV. FNRR holds promise for
detecting a broad range of conventional and improvised explosives, by determining the identity and
density distribution of light elements such as C, N and O within an inspected object. FNRR is also
employed to locate diamonds in a mineral rock environment.
This contribution reviews the various techniques of FNRR and examines their advantages and
shortcomings. The required FNRR system characteristics for detection of explosives, such as detection
efficiency, spatial resolution and energy resolution are outlined and some recent solutions aimed at
achieving these goals are presented.
