An apparatus for detecting neutrons includes a cerium activated scintillation crystal containing 10B, with the scintillation crystal emitting light in response to alpha particles emitted from the 10B(n, alpha )Li* reaction. The apparatus also includes a gamma scintillator positioned adjacent the crystal and which generates light in response to gamma rays emitted from the decay of Li*. The apparatus further includes a first and a second light-to-electronic signal converter each positioned to respectively receive light from the crystal and the gamma scintillator, and each respectively outputting first and second electronic signals representative of alpha particles from the 10B(n, alpha )Li* reaction and gamma rays from the 10B(n, alpha )Li* reaction. The apparatus includes a coincidence circuit connected to receive the first and second signals and which generates a coincidence signal when the first and second signals coincide. The apparatus also includes a data analyzer for receiving an additional signal from at least one of the first and second converters, and for operating in response to the coincidence signal.
