ABSTRACT:
A non-invasive inspection system employs the isotropic, resonant scattering of neutrons from an object to determine the presence of at least one preselected element therein. A monoenergetic neutron beam is impinged onto the object and a first detector is disposed to detect neutrons resonantly scattered by the preselected element. A second detector is disposed to detect non-resonantly scattered neutrons. Comparison of the signals from the two detectors is indicative of resonant scattering and hence presence of the preselected element.
