[Cytogenetic effect of low-level 60Co gamma-irradiation of cultured human lymphocytes in the G1 phase of the mitotic cycle].
The dose-dependence of the chromosome aberration frequency in human lymphocytes in vitro exposed to 60Co-gamma-radiation at the G1 stage of the mitotic cycle has proved to be unlike that obtained upon exposure of cells at the G0 stage of the cycle. The data obtained are accounted for by partial activation of the repair system at the G1 stage which is attributed mainly to chromatin decondensation.
