Abstract

A system of particle detectors can determine the location of a source without rotations or iterations. Embodiments of the system may include a middle detector flanked by two side detector panels, without shields or collimators. The middle detector may be positioned toward the front and orthogonal to the side detectors. By comparing a ratio of the detector data to a predetermined angular correlation function, the system can determine both the sign and magnitude of the source angle in real-time. Embodiments of the system can rapidly and automatically localize sources including industrial, medical, and other benign sources as well as nuclear and radiological weapons materials, whether in vehicles or cargo containers, and can provide improved sensitivity in walk-through personnel portal applications, enable enhanced detection of hidden weapons by a mobile area scanner, and enable a hand-held survey meter that indicates the radiation level as well as the location of the source of radiation.
