ABSTRACT:
A portable device used for non-destructive detection of illicit narcotics, or other hydrogen or light element containing substances, includes a weak, self-contained, radioactive source of fast neutrons and a detector for detecting scattered thermal neutrons and gamma rays. The detector design allows it to detect hermetically sealed or unsealed packages of narcotics or other materials concealed behind compartment barriers. The detector can also be used to detect the identity or type of material by simultaneously using both the gamma ray flux and thermal neutrons flux.
