A lightweight neutron remmeter for measuring neutron equivalent dose with a response range from the thermal energy levels to around 14 MeV is achieved using a center BF₃ proportional neutron detector moderated by enclosure within a cylindrical center tube and two adjacent BF₃ proportional neutron detectors. A cylindrical hydrogenous material covered by a boron loaded rubber wrap moderates the center detector within the center tube. The adjacent neutron detectors are uncovered. In this manner the center detector responds to fast neutrons and the over response to thermal and intermediate energy neutrons is corrected by the adjacent neutron detectors readings and an algorithm implemented by a RADIAC.
