Inspecting Minefields and Residual Explosives by Fast Neutron Activation Method.

As an upgrade of a robotic mobile system for anti-personnel landmine clearance, a fast neutron probe has been considered for the detection of mines and explosive residues. Laboratory tests were made by using the 14 MeV $6times 10^{; ; ; 7}; ; ; $ neutrons/sec beams with the associated alpha particle detection and with a ${; ; ; rm LaBr}; ; ; _{; ; ; 3}; ; ; $ gamma-ray detector. Simulant of the anti-personnel mine was used as a target. Several measurements were made with the target buried into the soil at different depths. For each depth minimal time measurement was estimated for false negative 0.4% and false positive equal to 10%. Tests showed that it is possible to detect buried landmines as well as residual explosives ; however, in order to reach the optimal speed of 10 cm/s of the demining vehicle it is necessarily to use several sealed tube neutron generators and few dozen of ${; ; ; rm LaBr}; ; ; _{; ; ; 3}; ; ; $ gamma-ray detectors.
