Thermal neutron activation and fast neutron scattering are known to be a us
eful tool to detect hidden explosives which present an elevated concentrati
on of nitrogen and peculiar elemental ratio for light elements (C, N, O). S
uch characteristics can be suitably optimized to detect the small amount of
explosives contained in anti-personnel mines (APM) disseminated in former
war theatres. We report here on a research program aimed at defining a conc
eptual design of a field operated system for APM detection based on neutron
induced reactions. (C) 1999 Elsevier Science B.V. All rights reserved.
