[The genome instability in the descendants of the Chinese hamster of the cells, irradiated by the low dose and by various intensities of gamma-radiation].
The V-79 Chinese hamster cells were irradiated by gamma-rays in dose of 0.5 Gy at powers of doses 0.48 Gy/min (an acute irradiation) and 0.0485 MGy/min (a prolonged irradiation). The acute and prolonged irradiation in a dose of 0.5 Gy enlarges frequency of the appearance of micronucleus (MN). Subsequent cultivation of the irradiated cells during 20 generations enlarges frequency of MN, and for prolonged an irradiation the boosted frequency of MN, is saved during 40-60 generations. After an acute irradiation the number of MN starts to reduce after 20 doublings.
