Fast-neutron dose rate vs energy for the d+Be reaction--a reanalysis.
The differences in the published information concerning tissue kerma in air vs deuteron energy for the d+Be reaction are analyzed in light of some recent measurements. The reason for the discrepancy is determined to be a lack of electron suppression on the Be target in some earlier measurements, and the relation ln(tissue kerma)=ln(1.356 X 10(-4)+2.97lnE is found to fit the measured data over the deuteron energy range 11-50 MeV.
