[The comparative radiosensitivity of the lymphocytes of men and women under gamma irradiation at the G0 stage of the mitotic cycle].
Radiosensitivity of male and female lymphocytes exposed to gamma radiation (60Co) in phase G0 of the mitotic cycle has been comparatively studied. The radiosensitivity was shown to be identical, within the limits of error, although with the recombination repair (the nonhomologous nature of X and Y chromosomes being taken into account) the number of chromosome aberrations in male cells must be 1.4 times larger than in female cells. This indicates an absence or (within the limits of error) an insignificant role of the recombination repair of double-strand DNA breaks.
