A resonance absorption method was used for calibrating neutron counters for personal neutron dosimetry.This facility used a 239Pu-Be neutron source placed inside an assembly of graphite blocks. The energy calibration of the proportional counters in the energy range of 50-1500 keV was comparable to using monoenergetic neutrons. Replacement of the 239Pu-Be source by a stronger 238Pu-Be source or a lower energy should reduce the counting time considerably and make the calibration simpler to perform.
