Abstract:
1. An apparatus for detecting a radiation source, the apparatus comprising: a first scintillator divided into discrete sections, wherein at least two of the discrete sections are structured with a different thickness; a second scintillator adjacent to the first scintillator; each of the first scintillator and second scintillator being structured to generate a light pulse responsive to interacting with incident radiation, the first scintillator being structured to experience full energy deposition of a first low-energy radiation, and permit a second higher-energy radiation to pass therethrough and interact with the second scintillator; and a plurality of light-to-electrical converters operably coupled to the second scintillator and configured to convert light pulses generated by the first scintillator and the second scintillator into electrical signals, wherein the first scintillator and the second scintillator exhibit at least one mutually different characteristic for an electronic system to determine whether a given light pulse is generated by the first scintillator or the second scintillator.
