  • Library generation for detection and identification of shielded radioisotopes
    Patent number: 9256713
    Abstract: A method, logic and system are provided for generating data representing all possible materials that may be present when monitoring a region or space for a radioisotope of interest. All possible materials with which a radioisotope material may interact are grouped or categorized into one of a plurality of material groups. Each material group is further subdivided into a plurality of subgroups based on atomic number of a material. First data is stored for each of the subgroups of each of the plurality of material groups, where the first data represents an interaction between a representative material for a corresponding subgroup and radiation at a plurality of energy levels. Second data is stored representing spectral characteristics of each radioisotope of interest at the plurality of energy levels.
