HORIZONTAL SENSOR ARRAYS FOR NON-INVASIVE IDENTIFICATION OF HAZARDOUS MATERIALS
First Claim
1. A method, with a frame structure comprising a first portion and a second portion configured to receive an entity to be examined therebetween, for detecting radiation and identifying materials associated with radiation that has been detected, the method comprising:
- determining that an entity to be examined has entered between a first portion and at least a second portion of the frame structure;
receiving from a set of radiation sensors mechanically coupled to the at least one portion of the frame structure, a set of radiation data associated with the entity, wherein the set of radiation sensors includes a plurality of radiation sensors situated in a horizontal configuration with respect to each other and a direction of travel through the frame structure associated with the entity currently being examined;
generating at least one histogram based on the set of radiation data, wherein the at least one histogram represents a spectral image of the entity;
comparing the at least one histogram to a plurality of spectral images associated with known materials;
determining that the at least one histogram substantially match at least one of the plurality of spectral images;
determining if a material associated with the at least one of the plurality of spectral images is a hazardous material; and
notifying personnel that the at least one radiation source is a hazardous material in response to determining that the material associated with the at least one of the plurality of spectral images is a hazardous material.

Abstract
A system, method, and frame structure detect radiation and identify materials associated with radiation that has been detected. An entity to be examined is determined to have entered between a frame structure. A set of radiation data is received from a set of radiation sensors mechanically coupled to a portion of the frame structure. The set of radiation sensors includes multiple radiation sensors situated in a horizontal configuration with respect to each other and a direction of travel through the frame structure associated with the entity currently being examined. At least one histogram is generated based on the set of radiation data. The at least one histogram is compared to a plurality of spectral images associated with known materials. The at least one histogram is determined to substantially match at least one of the plurality of spectral images. Personnel are notified that the at least one radiation source is a hazardous material.
