Multi-stage system for verification of container contents
First Claim
1. 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.

Abstract
A multi-stage process utilizing one or more radiation sensors on a distributed network for the detection and identification of radiation, explosives, and special materials within a shipping container. The sensors are configured as nodes on the network. The system collects radiation data from one or more nodes and compares the collected data to one or more stored spectral images representing one or more isotopes to identify one or more isotopes present. The identified one or more isotopes present are corresponded to possible materials or goods that they represent. The possible materials or goods are compared with the manifest relating to the container to confirm the identity of materials or goods contained in the container or to detect and/or identify unauthorized materials or goods in the container. For shielded materials, explosives and other types of material detection, a neutron pulse device could be incorporated into the system.
