[Biological effectiveness of fast neutrons with a mean energy of 22 MeV].
Biological effectiveness of fast neutrons of a mean energy of 22 MeV obtained by the reaction d[50 MeV]----Be, measured by the death rate, was substantially lower than that of division spectrum neutrons of a mean energy of 1.2 MeV. LD50/30 of the division spectrum neutrons was within 2.57 +/- 0.07 Gy and that of 22 MeV fast neutrons 4.79 +/- 0.13 Gy. The RBE coefficient for the studied neutrons was 1.34 +/- 0.05 as estimated by LD50/30 and 1.5 +/- 0.1 as determined by D37 for a cell model of radiation affection.
