MORBIDITY OF HEMOBLASTOSES IN ROVENSKY DI STRICT OF UKRAINE BEFORE AND AFTER CHERNOBYL AES ACCIDENT

Hemoblastose morbidity in children and adult populations and its struc ture were studied during the period of 1981-1992 at Rovensky district of Ukraine, 6 northern districts of which were affected by radionuclid es after Chernobyl AES accident. Primary documentation, actual and arc hival records were the object of study: registration diaries, records and ambulatory cards. Expeditional method of investigation. During the last 11 years a rise of hemoblastose morbidity was stated in Rovensky district, especially after the accident, and it was confirmed by a pr ofound statistical analysis of data on leukemia morbidity before and a fter the accident. Among different nosological forms after the acciden t the rate of leukemia morbidity as well as myeloma disease and malign ant lymphoma morbidity, rose markedly. No significant difference was m arked in hemoblastoses (excluding acute leukemia) in non-contaminated and contaminated with radionuclides regions of the district, and in co ntaminated zones depending on effective equivalent doze. Acute leukemi a morbidity in contaminated regions after the accident was statistical ly reliably higher.
