title: [Effect of gamma irradiation on human chromosomes in vitro. IX. The ratio of the yield of aberrations to the time of cell fixation in GO-stage irradiation].
abstract: The dependence of the chromosome aberration yields on the sampling time was studied in the culture of human lymphocytes after different doses of gamma-irradiation in the stage G0. It was shown that the cells irradiated in the stage G0 had the constant aberration frequency during the first division after irradiation (45 to 55 hours). The distribution of aberrations among the cells examined at first division was poisson. These results are interpreted in favour of homogeneous chromosomal radiosensitivity of the population of PHA-responsive lymphocytes.
