The work concerns the assessment of radiation risks for non-cancer diseases of circulatory system among the Chernobyl liquidators. The medical and dosimetric data from Russian National Medical and Dosimetric Registry were used. The cohort data from 1986 to 2000 years of 61017 liquidators are discussed. Radiation risks are established for the cerebrovascular diseases and for the essential hypertension the significant. ERR =0.45/Gy, with 95% CI = (0.11; 0.80) for the cerebrovascular diseases and ERR = 0.36/Gy, with 95% CI = (0.005; 0.71) for the essential hypertension. It approves the results which were established by authors for the similar cohort in 1986-1996. The cerebrovascular diseases (CVD) are considered in greater details. The significant heterogeneity of the radiation risks by working time in Chernobyl zone is shown for the first time. ERR = 0.89/Gy for the working time less then 6 weeks, and ERR = 0.39/Gy in average for all periods of working in the zone. Among the liquidators entered Chernobyl zone during the first year after the accident (29003 liquidators), the CVD's risk group consists of persons accumulated more then 150 mGy from external sources in less, then 6 weeks (RR = 1.18 with 95% CI = (1.00; 1.40)). The significant CVD's risk from averaged dose rate was defined for external doses greater then 150 mGy (ERR for 100 mGy/day = 2.17, with 95% CI = (0.64; 3.69)). |
