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(1.356×10 −4 )+2.97 ln E is found to fit the measured data over the deuteron energy range 11–50 MeV.
