[Relative biological effectiveness of gamma-neutron irradiation with neutron energy of 0.9 MeV].
Relative biological effectiveness (RBE) of gamma-neutron radiation with neutron energy of 0.9 MeV was estimated with a reference to rat death. It was shown that RBE of gamma-neutron radiation (the share of neutrons was 67% as related to dose) at LD33/30 and LD100/30 was 2, and RBE of 0.9 MeV neutrons, in experiments with mixed radiation, was 3.1 and 2.86 at LD33/30 and LD100/30, respectively. The value of a maximum dose at which death was not registered during 30 days, was 1 Gy with gamma-neutron radiation and 4 Gy with X-radiation.
