Patent ID: 7760103

Claim:
A method for detecting and identifying radioactive materials within one or more containers, the method comprising: collecting, by a plurality of radiation sensors situated on at least one frame structure located outside of and in proximity to a container, at least one spectral data set representing radiation data associated with the container and its contents, the container being located in proximity to the plurality of radiation sensors; spectrally analyzing the collected at least one spectral data set associated with the container and its contents; identifying, based on the spectrally analyzing the collected at least one spectral data set, one or more isotopes associated with the contents within the container; identifying materials associated with one or more of the identified one or more isotopes; comparing the materials that have been identified to at least one manifest associated with the container, wherein the at least one manifest lists a set of materials that are declared to be within the container; and storing a set of comparison results in memory, the set of comparison results being associated with the comparing the materials that have been identified to at least one manifest associated with the container.
