The detection of personal mines is one of the most discussed problems today. If these mines have any metallic components, a sensitive metal detector can give some indication. The false alarm rate is high. Combining the signal of this method with that of a neutron backscatter (NBS) detector, which reflects the possible presence of explosives, the information is improved and false alarms should be reduced. A 2 channel detector is discussed. If there are personal mines without metallic parts than only a NBS-detector has a chance to give any information.
