Abstract
A Cf-252 fast-neutron transmission method for bulk detection of nitrog en-rich explosives, concealed in passenger luggage, is presented. The technique utilizes the cross-section resonances of two elements domina nt in explosives (nitrogen and oxygen). These resonances are portrayed in the pulse-height distribution of transmitted neutrons measured wit h a helium-3 detector. Monte Carlo simulations are used to support the theoretical concept of the method. The feasibility of the technique i s demonstrated in the laboratory employing an explosive-like material (nitrogen-rich fertilizer). (C) 1997 Elsevier Science Ltd.
