An apparatus and method for detecting neutrons, particularly, with directional sensitivity. The apparatus is a detector with a scintillator containing high neutron-capture-cross-section atoms for capturing neutrons and emitting electromagnetic radiation, and an optical detector for detecting the emitted electromagnetic radiation and for generating an electrical signal. The high neutron-capture-cross-section atoms may be gadolynium, in particular, and the detector may additionally have a moderator for converting fast neutrons into thermal neutrons that are then captured by the high neutron-capture-cross-section atoms.
