Abstract:
1. A method for identifying materials of interest within an enclosure, the method comprising: a. rotating the enclosure about a first axis; b. obtaining a three-dimensional image indicative of at least one of a CT number and density of contents of the enclosure; c. identifying a suspect region of contents of the enclosure based on at least one of the CT number and density; d. activating a collimated neutron beam to traverse a suspect region; e. rotating a collimated gamma radiation detector about a second axis noncoincident with the first axis such that the detector intercepts fluorescent emission from the suspect region traversed by the collimated neutron beam; f. detecting fluorescent emission from the suspect region; and g. characterizing material within the suspect region based at least on the detected fluorescent emission.
