EPIDEMIOLOGIC REGISTER OF LEUKEMIA AND OT HER HEMOBLASTOSES IN BRYANSKY DISTRICT AS AN INSTRUMENT OF INVESTIGATION OF CONSEQUENCES OF CHERNOBYL ACCIDENT

Beginning from 1986, at Hematological Research Centre (HRC) epidemiolo gical monitoring has been performed on haemoblastoses in Bryansky dist rict, which suffered from the Chernobyl accident more than any other a rea of Russia. The collection of personal information is organized abo ut each case of disease from all possible sources, diagnosis verificat ion, computer control, storage and analysis of materials. A specialize d Register of Blood diseases is created, including demographical and e cological files. Retrospective period of monitoring 1979-1985, afterac cident period-from 1986. In the register 2832 cases were accumulated o f haemoblastoses up to 1993. Regions are selected for monitoring with high levels of contamination by Cs-137 (15 Ci/sq.km and more), and are a for comparison-the others 21 regions of the district. The comparison did not reveal substantial differences. Further epidemiological analy sis must be performed. Taking into account dose loads, special studies are initiated.
