The signature-based radiation-scanning technique for detection of improvised explosive devices is described. The technique seeks to detect nitrogen-rich chemical explosives present in a target. The technology compares a set of “signatures” obtained from a test target to a collection of “templates”, sets of signatures for a target that contain an explosive in a specific configuration. Interrogation of nitrogen-rich fertilizer samples, which serve as surrogates for explosives, is shown experimentally to be able to discriminate samples of 3.8 L and larger.
► Signature-based radiation-scanning techniques applied to detection of explosives.
► Nitrogen-rich fertilizer samples served as surrogate explosive samples.
► Signatures of a target compared to collections of templates of surrogate explosives.
► Figure-of-merit determined for neutron and neutron-induced gamma-ray signatures.
► Discrimination of surrogate explosive from inert samples of 3.8 L and larger.
