Application of Different Orthonormal Expansion Methods to Neutron Measurements. III. Actual Measurements of Spectra and Dose Equivalent Rates

Neutron spectra and dose equivalent rates were measured with a BF 3 proportional counter covered with two, three or five of 0-, 3.5-, 4.5-, 6.5-, 8.5- and 14.0-cm-thickness paraffin moderators. The dose equivalent rates were also measured with a “Remcounter” having two detectors, one of which consis...

Summary:Neutron spectra and dose equivalent rates were measured with a BF 3 proportional counter covered with two, three or five of 0-, 3.5-, 4.5-, 6.5-, 8.5- and 14.0-cm-thickness paraffin moderators. The dose equivalent rates were also measured with a “Remcounter” having two detectors, one of which consists of a BF 3 counter centered in 30-cm-diameter paraffin cylinder and the other of three BF 3 counters embeded at intervals of 120 degrees along a coaxial 16-cm-diameter cylinder in the same paraffin moderator. The obtained dose equivalent rates for neutrons from a RaD-Be source did not differ by more than 22 per cent from the theoretical values given in the paper II, even when the measured spectra had large negative values at some energy.
