Radiation imaging systems provide a wealth of information for analyzing quantities of interest (enumeration, strength, dimensions) of an uncharacterized source. This capability is useful, for example, when measuring plutonium powder “held up” in unknown locations at reprocessing facilities. Accurate models of the imager are required to infer the quantity of interest. This paper describes the modeling...

Radiographic detection of such threat objects relies on high image contrast...
