Container verification system for non-invasive detection of contents
First Claim
1. A radiation detection and identification system, comprising:
- a frame structure;
one or more gamma sensors;
one or more solid-state neutron sensors, wherein the one or more gamma sensors and the one or more solid-state neutron sensors being collectively mounted on the frame structure that can be located in proximity to a container under examination;
a digital data collection system, communicatively coupled with the one or more gamma sensors and the one or more solid-state neutron sensors, for collecting radiation data from the one or more gamma sensors and the one or more solid-state neutron sensors;
a multi-channel analyzer system, communicatively coupled with the digital data collection system, for preparing histograms of the collected radiation data;
a spectral analysis system, communicatively coupled with the multi-channel analyzer system and the digital data collection system, for receiving and analyzing the collected radiation data and the histograms to detect radiation and to identify one or more isotopes associated with the collected radiation data;
a first data storage means for storing data representing isotope spectra for use by the spectral analysis system, where one or more spectral images stored in the first data storage unit represent each isotope, the first data storage means being communicatively coupled with the spectral analysis system;
an information processing system, communicatively coupled with the spectral analysis system, for analyzing the identified one or more isotopes and to determine the possible materials or goods that they represent; and
a second data storage means for storing data representing a manifest relating to the container under examination, the second data storage means being communicatively coupled with the information processing system, the information processing system further for comparing the determined possible materials or goods with the manifest relating to the container under examination to determine if there are unauthorized materials or goods contained within the container under examination.

Abstract
A radiation, explosives, and special materials, detection and identification system includes a housing supporting one or more gamma sensors and one or more solid-state neutron sensors proximate to container contents under examination. The system collects radiation data from the sensors 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. A battery powered sensor arrangement is also disclosed.
