A computer program, database and method for the detection of fissile or radioactive material or radiation shielding material in a container works with detection devices brought into proximity to containers so that the presence of fissile or radioactive material, or shielding materials to conceal the presence of such fissile or radioactive materials, may be detected. A comparison may then be made of the output of the detector to a threshold to determine subsequent action regarding the shipping container. The threshold may be based on the output of known, dangerous radioactive materials, known legitimate contents or empty containers.
RELATED APPLICATION DATA
The present application is a continuation-in-part of the commonly owned, application for patent having at least one inventor in common herewith and entitled "Container Crane Radiation Detection Systems and Methods," Ser. No. 10/356,154, filed Jan. 31, 2003 now U.S. Pat. No. 6,768,421, the specification of which is incorporated herein by reference.
A passive radiation sensor suitable for homeland security applications or other monitoring of locations deemed at high risk to radiation exposure. The sensor further incorporates a method to provide a statistically derived detection threshold algorithm that guarantees a predetermined and configurable false-alarm rate and rapid detection of low-level radiation.
An apparatus and methods for improving the ability of a detection system to distinguish between a "true attack" as opposed to a nominal increase in a monitored environmental characteristic.
A shielding detection system for cargo receptacles includes an inertia test apparatus configured to detect mass and inertia data of a cargo receptacle. The inertia test apparatus provides an indication of the presence of shielding within the cargo receptacle.
