1. A detector for detecting nuclear radiation threats, the detector comprising:

  • a plurality of elongate scintillator segments arranged in a side by side array;

    at least one pair of light sensors optically coupled to ends of each of the elongate scintillator segments such that they receive light from scintillations produced in the scintillator segments and generate electrical signals responsive thereto; and

    a controller that identifies a plurality of scintillations as emanating from a single incident particle based on a time window within which they fall and their spatial proximity within the detector.
