Long-term cohort epidemiological studies on circulatory diseases among the Chornobyl clean-up workers 19861987 have been conducted on the data of the State Chornobyl Registry of Ukraine. There was established a significant increase in acute cerebrovascular diseases (stroke, infarction, etc. (430.0436.9 ICD-9; 60.066.0 ICD-10), the latter being the main cause of early disability and mortality in postaccident period (19982009). There were revealed some age-specific features of the above pathology incidence in the age group 40 years and older at the time of exposure was significantly higher compared to the age group under 40 throughout the study; but in the dynamics of observation growth rates were higher in younger age group. We have found the significant relative risks for acute cerebrovascular diseases among the Chornobyl clean-up workers 19861987 younger than 40 at the time of exposure with whole body dose 0.250.7 Gy during 19982002 (RR=1.38(1.01;1.89), ERR (Gy1)=0,8), the dose range 0.050.7 Gy in the period 20032007 (RR=1.67(1.28;2.17), ERR (Gy1)=8.9); among persons over 40 at the time of exposure with whole body dose 0.10.199 1722 years after the Chornobyl accident (RR=2.18(1.46;3.25), ERR (Gy1)=7.8).

Key words: morbidity, acute cerebrovascular diseases, the Chornobyl clean-up workers, risks.
