[en] A modified design of scintillation neutron detector, consisting of a scintillator, around which a moderator and a resonance absorber are located, has been suggested. For widening the energy range of recorded neutrons by means of its sensitivity levelling to slow neutrons the detector is additionally surrounded by perforated absorber of slow neutrons, made of cadmium foil. The area of perforation is selected on the basis of the ratio: epsilon sub(slow)/epsilon sub(fast)=Ssub(irrad)/Ssub(perf), where epsilon sub(slow)-sensitivity to slow neutrons; epsilon sub(fast)-sensitivity to fast neutrons; Ssub(perf)-perforation area; Ssub(irrad)-detector surface irradiated area having identical sensitivity to slow neutrons. The detector described can be used as a sensitive element in industrial radiometers. Therefore, in ''Kran'' type radiometers the detector considered can be substituted for a set of three detectors presently used. It permits to simplify considerably the measuring procedure
