[1] Twenty years after the chernobyl accident - is it much or not? / I. I. Pelevina, G. G. Afanasjev, V. Y. Gotlieb, A. A. Konradov // 20 Years After the Chernobyl Accident: Past, Present and Future. — Nova Science Publishers, Inc N.N. Semenov Institute of Chemical Physics, Russian Academy of Sciences, 4 Kosygin street N.M. Emanuel Institute of Biochemical Physics, Russian Academy of Sciences, Moscow, 2007. — P. 331–343. The results of long-term investigations, implemented in the zones affected by the Chernobyl accident consequences are presented. They were obtained for the cells in tissue culture, laboratory animals (mice), blood lymphocytes of citizens from contaminated areas (children and adults). It is concluded that the presence in contaminated areas induces genomic instability observed in a multiplicity of effects at cytogenetic, cellular and organism levels. It is indicated that in late generations after exposure to radiation, in the accident zone intensified cell death, increased level of micronuclei, giant cells, elevated radiosensitivity, and the absence of the adaptive response are observed. The culture of embryonic fibroblasts from exposed mice demonstrated elevation of the number of cells with chromosomal aberrations and the frequency of cells with multiple chromosomal aberrations. The mice exposed to radiation in the accident zone demonstrated decreasing number of endotheliocytes in different parts of cerebrum and increased radiosensitivity of animals. The above-described effects are observed in late cell generations and may be a product of low dose radiation-induced genomic instability. © 2006 by Nova Science Publishers, Inc. All rights reserved.
