Abstract
Methods for selecting and applying test criterion for use in the radiation analysis of contents of objects, based on whether the contents of the object, or contents of portions of the object, comprise inorganic or organic material, are described. In one example, the object is scanned by radiation and the contents type is determined based on preliminary test criterion adapted to distinguish between inorganic material and organic material, and detected radiation. At least one test criterion is selected based, at least in part on the determination and it is then determined whether the object at least potentially contains material having an atomic number greater than a predetermined atomic number based, at least in part, on the detected radiation and the at least one selected test criterion. Systems are also disclosed.
