Abstract:
A radioactive material detection system includes a plurality of radioactive material detection apparatuses and a master unit/master module. Each apparatus is disposed in or on a cargo receptacle and each apparatus has a wireless transmitter, a radiation sensor and a detection controller. The master unit/master module has a receiver configured to receive the wirelessly transmitted information from each of the wireless transmitters and a master controller. The system detects fissile or nuclear material that emits radiation by (i) calculating and storing at the master unit/master module an initial average measured radiation level at each radioactive material detection apparatus location throughout the entire array of radioactive material detection apparatuses and (ii) comparing the current measured radiation at each radioactive material detection apparatus location to the initial radiation level at each location in order to identify an anomaly amongst the plurality of cargo receptacles.
Abstract:
The present specification discloses systems and methods for integrating manifest data for cargo and light vehicles with their X-ray images generated during scanning. Manifest data is automatically imported into the system for each shipment, and helps the security personnel to quickly determine the contents of cargo. In case of a mismatch between cargo contents shown by manifest data and the X-ray images, the cargo may be withheld for further inspection. In one embodiment, the process of analyzing the X-ray image of the cargo in conjunction with the manifest data is automated.
Abstract:
A mobile detecting apparatus (10, 12, 14, 16) which can include the ability to transmit data to and receive instructions from a remote location, detect multiple objects (e.g. stacked or side by side containers or cargo), and provide efficient traffic flow (e.g. at cargo port).
Abstract:
A radioactive material detection system (200) includes a cargo container monitoring system (10) and a control center (220). The cargo container monitoring system (10) has a radiation sensor (24) configured to detect radiation over a predetermined or commanded period of time and a transceiver (26) configured to send the information received from the radiation sensor (24). The control center (220) is in communication with the transceiver of the cargo container monitoring system (10). The control center (220) is configured to receive data from at least one additional source (222) other than the cargo container monitoring system (10) and to asynchronously analyze the data from the at least one additional source (222) and the information from the radiation sensor (24), during transit, so as to detect radioactive material in a cargo container (12).
Abstract:
A central system of monitoring radiation levels in a plurality of facilities at the same time is disclosed. The system may include radiation detection systems, a processor to process monitoring data generated by the radiation detection systems to compensate for naturally occurring radiation, and a central monitoring station capable of generating an alarm at the central monitoring station and at a facility where an undesired radiation level has been detected. A method of monitoring radiation levels in production facilities is also disclosed. The method may include providing a plurality of radiation detection systems, providing a central monitor in communication with the radiation detection systems, communicating data from the radiation detection systems to the central monitor, and analyzing the data to detect potential radioactive materials.

Abstract:
A method for screening and tracking items of cargo to be shipped aboard a vehicle includes steps of scanning the items to generate x-ray image data of the items; subjecting the image data to computer implemented image recognition to identify the items; presesenting images generated from the image data to a human operator trained in object recognition; reviewing the images with the human operator; recording the result of the human operator's review, wherein the human operator is one of a number of such operators at one or more locations who have access to or receive image data for items to be shipped for each item determining if the results from the computer implemented and human review meet criteria for items that should not be shipped, and loading items which are to be shipped into a shipping container.
Abstract:
A multi-stage process detects and identifies radiation, explosives, and special materials within a shipping container. The process utilizes radiation sensors configured as nodes on a distributed network. The process collects radiation data from the nodes. The radiation data is associated with the container and its contents. The collected radiation data is dynamically adjusted according to dynamically changing background radiation data, such as relating to water, land, air, ground, and other structures. The process compares collected and adjusted radiation data to spectral images representing isotopes to identify one or more isotopes present. Identified isotopes are corresponded to possible materials that they represent. The possible materials are compared with the manifest of the container to confirm the identity of materials contained in the container or to detect and/or identify unauthorized materials in the container. A neutron pulse device could be used to identify shielded materials, explosives, and other types of materials.
