Abstract
Neutron backscattering was selected as a promising new method for the detection of landmines. With this technique, /sup 252/Cf source and a thermal neutron detector are used. Fast neutrons from the Californium source are better moderated by the landmine, especially plastic mines, than in the surrounding soil. This leads to an increase in the number of reflected thermal neutrons above the mine. Results from experimental trials with the Delft University Neutron Backscattering Landmine Detector (DUNBLAD) are presented and compared with results from Monte Carlo simulations. The limitations of this method and the radiation dose for the user are investigated. Based on these results, a new portable prototype detector is presented.
