1. An apparatus for selective radiation detection, comprising:
- a first light guide, optically coupled to a first optical detector;
a second light guide, optically coupled to a second optical detector, said second light guide comprising a gamma ray scintillator material;
a sheet of neutron scintillator, opaque for incoming optical photons, said sheet of neutron scintillator sandwiched between the first and the second light guides; and
a processor, coupled to the first and second optical detectors, configured to classify detected radiation as neutrons or gamma rays depending on whether signals generated by the first and second detectors are concident.

Abstract
An apparatus for selective radiation detection includes a neutron detector that facilitates detection of neutron emitters, e.g. plutonium, and the like; a gamma ray detector that facilitates detection of gamma ray sources, e.g., uranium, and the like. The apparatus comprises a first light guide, optically coupled to a first optical detector; a second light guide, optically coupled to a second optical detector a sheet of neutron scintillator, opaque for incoming optical photons, said sheet of neutron scintillator sandwiched between the first and the second light guides. The second light guide comprises a gamma ray scintillator material.
