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.
本文展示了关于X射线对两个不同地理种群的棕背䶄骨髓细胞染色体畸变发生率和有丝分裂活性影响的数据。结果表明，在照射（350伦琴）后的不同时间间隔，莫斯科种群中异常细胞的百分比高于科米自治共和国种群。分次辐射导致异常细胞数量有不同程度的增加。在这两个地理种群中，X射线照射后有丝分裂活性的变化也有所不同。
