[Polyploidization of rat hepatocytes due to cell fusion caused by radiations of different LET].

The method of flow cytometry was used to study polyploidization of hepatocytes following X-, gamma-, and neutron-irradiation. Ionizing radiation was shown to induce cell polyploidization by two different ways: (1) cells and nuclei fusion, and (2) restriction of mitosis after DNA replication. RBE of 14 MeV neutrons with respect to fusion was about 5.
