[Results of cytogenetic screening of people employed in liquidation of accident consequences at the Chernobyl nuclear plant in 5 years].

The liquidators of Chernobyl power station accident consequences were subjected to cytogenetic examination in 5 years after the accident. The analysis included a routine method of peripheral blood lymphocyte culture. The exposed and reference groups turned out to differ in the occurrence of distorted cells and chromosomal aberrations in peripheral blood lymphocytes. The highest cytopathogenic effect was seen in those, who had been working at the station in May-June 1986. The authors suggest to form the groups at high risk on the base of cytogenetic data and subject the groups to thorough examination for various diseases including malignancies.
