The article presents the data on biological effectiveness of neutrons generated by the pulsed reactor BARS-6 (dose-rate up to 6 x 10(6) Gy/s) in comparison with fast neutrons of the reactor BR-10 (dose-rate 6.3 x 10(-2) Gy/s). It was shown for yeast cells of a wild type that the RBE values of pulsed neutrons varied insignificantly with a dose (2.0-1.7) white for continuous neutron irradiation clear RBE dependence on the dose was observed. It was also found that the yeast cells had identical capability of postirradiation recovery in non-nutrient medium (LHR) following both gamma-irradiation and neutron exposure irrespective of neutron dose-rate.
