[The cytogenetic assessment of the degree of severity of acute radiation sickness in those who cleaned up the Chernobyl catastrophe].

The study is of a retrospective character and is based on the author's own cytogenetic findings secured in May-June 1986 in the examination of patients diagnosed as having had a first to third-degree acute radiation sickness while receiving massive detoxicating therapy. We consider it expedient to employ the model of multiple linear regression relying on a complex of most informative cytogenetic indicators rather than on only one such indicator alongside the traditional dose reaction identifiable by the level of dicentric chromosomes in blood lymphocytes. This will allow the degree of severity of the radiation injury to be determined with greater precision and permits assessing the therapeutic efficiency of the measures implemented.
