title: [Long-term cytogenetic effects in children prenatally-exposed to radiation as a result of the accident at the Chernobyl Atomic Energy Station].
abstract: Forty-two children exposed to ionizing radiation in prenatal period and 15 children of control group were examined in the remote terms after the accident using the method of differential G-staining of chromosomes in lymphocytes of peripheral blood. It was found that the average group rate of aberrant cells and chromosome aberrations was reliably higher in the children exposed in utero compared to control. Long-term cytogenetic consequences of the pre-natal exposure were characterized by prevalence of aberrations of a chromosome type, mainly stable chromosome lesions. At chronic exposure to low doses of ionizing radiation the increase in the rate both stable and unstable chromosome aberrations.
