Claim:
1. A device for detecting and discriminating between neutron signals and gamma ray signals, comprising: a composite scintillator material comprising an organic scintillation phase comprising a polymer and an organic dye, and a distinct inorganic high-Z phase comprising high-Z atoms having an atomic number of at least 45; an optically transparent element comprising a glass or polymer sheet doped with gadolinium oxide; wherein the optically transparent element is surrounded by layers of the composite scintillator material; one or more photomultiplier tubes adjacent to the composite scintillator material; and a processor coupled to the photomultiplier tube programmed to measure pulse heights of signals received from the photomultiplier tube, discriminate signals having pulse heights less than a predetermined threshold, and record the detection of a neutron when the pulse height of a signal exceeds the predetermined threshold.
