Nuclear Application to Hummanitatarian Landmine Detection

A compact discharge-type fusion neutron source called IECF (Intertial-Electrostatic Confinement fusion) device are presented that were and are being developed at Institute of Advanced Energy, Kyoto University. A 5 year task is also presented on the research and development of the advanced humanitarian landmine detection system aiming at cleaning of contaminated area in Afghanistan by using the IECF device and and 3 dual sensors made of BGO and Nal. With 107 D-D neutrons/s stably produced in CW, H-2.2 MeV, N-5.3, 10.8 MeV γ rays from (n, γ) reaction with nitrogen atoms in the explosives are measured for two kinds of explosives (TNT, RDX), under the conditions of three different buried depths, and soil moistures. Final detection probabities for arid soil are to be 100% in the present tests.
