title: [Cytogenetic differences in radiation effects on red-haired field mice from different geographic populations].
abstract: The paper presents the data on the effect of X-rays on the incidence of chromosome aberrations and on the mitotic activity of bone marrow cells in two geographical populations of Clethrionomys glareolus. It is shown that the percentage of aberrant cells at different intervals after the irradiation (350 r) is higher in the Moscow population than in the Komi ASSR population. The fractionation radiation results in different increase in the number of aberrant cells. The change of the mitotic activity after X-irradiation was also different in these two geographical populations.
