CONCEALED EXPLOSIVES DETECTOR BASED ON PORTABLE NEUTRON GENERATOR
The problem of detection and identification of hazardous substances became very urgent during last years. Nuclear physics methods allow one to perform standoff analysis of the suspicious object, determine its chemical composition, and decide if this substance is an explosive or any other hazardous material. In particular, methods of non-destructive neutron analysis, when object is exposed to neutrons and secondary neutron and/or gamma-radiation is registered, are successfully used in some systems [1–3]. In recent years systems like these are being equipped with pulsed neutron generators instead of radioisotope neutron sources. Neutron generators have essential advantages over radioisotope neutron sources. Among them are:
