A New Rem-Counter for Neutrons

Abstract

A new Rem-counter for neutrons was designed. The counter has two detector systems, one of which is a BF, counter embedded along the center axis in a 30-cm-diameter and 32-cm-height paraffin cylinder, and the other, three BF, counters embedded coaxially at intervals of 120 degrees around this axis.By using this counter, dose equivalent rates are measured within +30 per cent of errors for neutrons of typical spectra. The rough estimations of neutron spectra are also given by this Rem-counter.
