A self-powered neutron detector has a neutron-sensitive emitter, a collector enclosing this emitter and insulation between these two components. When irradiated by neutrons, the emitter generates Compton electrons so that a current is produced between the emitter and electrode and which may be used with a current-measuring device to provide a readout. The emitter is enclosed and electrically connected with a metal which is substantially neutron-insensitive so that the detector provides a substantially true and prompt signal accurately reflecting the neutron flux density received by the detector. |
