Nondestructive inspection of chemical weapons combining neutron activation analysis and neutron radiography techniques
A preliminary design for a transportable neutron system has been made for nondestructive detection of weapon materials such as chemical agents or explosives. The system combines imaging and identifying techniques and uses a SODERN sealed tube neutron generator GENIE 46. The neutron emitting module is embedded in a moderator/collimator. The resulting mixed 14 MeV and thermal neutron beam allows the performance of neutron radiography and neutron activation analysis. Substances to be detected are imaged in a first step and then identified by comparing relative spectral line intensities with those of reference materials. The moderator provides a first level protection against radiations to the operators. The system includes only industrial sub-assemblies, transportable by truck to be used in open areas.
