[Effect of chronic irradiation on the cell cycle of rat myelokaryocytes].
Rats were exposed to gamma-radiation within dose range from 0.12 to 4.0 Gy at dose rates from 0.625 microGy/s to 1.1 mGy/s. The changes in myelokaryocyte distribution within the cell cycle phases during the period of 1 to 18 months after irradiation were studied by the method of flow cytometry. A dose-dependent increase of cell percentage in S-phase after irradiation at low dose rates (from 0.625 to 10.0 microGy/s) was found. The effect was kept till the end of irradiated rats life.
