Abstract
The principle of the solution consists in gamma radiation, originating when catching slow neutrons by atom nuclei of nitrogen, contained in the plastic explosive, which is treated by neutrons from californium - 252. The device consists of a source (1) of neutrons from californium - 252 and a gamma radiation detector (3). The source (1) of neutrons is arranged in bismuth case (4) positioned in a hydrogen moderator (5), through which passes the conveyor (6) with luggage (12).<IMAGE>
