title: [The results of a cytogenetic examination performed in different years on those who worked in the cleanup of the aftermath of the accident at the Chernobyl Atomic Electric Power Station].
abstract: Persons participated in the Chernobyl accident amelioration in the years of 1986-1987 were examined cytogenetically either in 1987 (group 1) or in 1990-1992 (group 2). The frequency of chromosome aberrations in cultured peripheral lymphocytes is found to be significantly lower in group 2 in comparison with group 1, being increased in both exposed groups as compared to the control one. The data are obtained in favour of hypothesis on chromosome instability of exposed individuals. On the base of cytogenetic data the collective dose received by amelioraters was calculated.
