[Problem of radiation-induced leukemia].

Abstract A case of radiation-induced leukemia has been described in a woman living in the area exposed to radioactive contamination as a result of the disaster at the Chernobyl NPS. Radiation-induced leukemia was diagnosed basing on the cytogenetic changes in the bone marrow and peripheral blood lymphocytes. Cytogenetic changes in the peripheral blood lymphocytes have been recorded in 60 subjects who were evacuated from areas contaminated with isotopes as a result of the disaster.
