ABSTRACT:
A portable directional gamma ray radiation detector having a plurality of gamma ray radiation detectors separated by lead shielding arranged in an enclosure. Outputs from the detectors are applied to a signal processor to determine the location of a gamma ray emitter, and the signal processor is connected to a display device on the detector that indicates the direction to the gamma ray emitter.
