[The use of the FISH method for reconstructing the absorbed doses received by participants in the clean-up of the accident at the Chernobyl Atomic Electric Power Station].

The frequency of stable translocations using two-color fluorescence in situ hybridisation (FISH) were determined in peripheral blood lymphocytes of 20 persons who took part in liquidation of the Chernobyl accident and of 11 persons of control group. The individual doses for all patients were estimated from a calibration dose-response curve for stable translocation. The doses estimated by our cytogenetic data not always coincided with official dosimetric data. The possibility of using FISH for dose reconstruction of past radiation exposure was discussed.
