Disclosed is a directional gamma ray or neutron detector that locates a source both horizontally and vertically. In some embodiments, the detector comprises four rod scintillators around a shield, and an orthogonal panel scintillator mounted frontward of the rod scintillators. The azimuthal angle of the source may be calculated according to the detection rates of the rod scintillators, while the polar angle of the source may be calculated from the panel scintillator rate using a predetermined angular correlation function. Thus, the exact location of the source can be found from a single data set without iterative rotations. Embodiments of the detector enable rapid detection and precise localization of clandestine nuclear and radiological weapons in applications ranging from hand-held survey meters and walk-through portals, to vehicle cargo inspection stations and mobile area scanners. Such detectors are needed to detect clandestine nuclear weapons worldwide.
