Abstract
Current radiographic methods are limited in their ability to determine the presence of nuclear materials in containers or composite objects. A central problem is the inability to distinguish the attenuation pattern of high-density metals from those with a greater thickness of a less dense material. We have developed a method for using spectrally sensitive detectors to discriminate nuclear materials from multiple layers of other materials using single or multi-view radiographs. An inverse algorithm with adaptive regularization is central to the technique and allows for hands off use with minimal operator input.
