[Effect of gamma-irradiation and neutrons on DNA-membrane complexes in mammalian cells]

The first results of the radiobiological studies obtained in a biophysical channel of the IBR-2 reactor at the Joint Institute for Nuclear Research are presented in this report. A study was made of the DNA-membrane complex sedimentation after exposure of Chinese hamster cells V79-4 to gamma-rays within a wide range of doses. The assumption, that had earlier been forwarded by the authors, of the role of double-strand DNA breaks in the alteration of a relative rate of the complex sedimentation upon irradiation of cells with doses above 50 Gy was confirmed.
