Risk Assessment of Radiation-Induced Thyroid Cancer in Population of Belarus M.V.Malko Institute of Power National Academy of Sciences of Belarus, Minsk, Belarus

The incidence in thyroid cancer in the Belarusian population are presented in the report. It was found that approximately 8,700 additional thyroid cancers occurred in Belarus in The number of thyroid cancers registered in Belarus in this period is about 13,300 cases (4,600 expected cases). The relative risk averaged for this period is equal to 2.89 (95% CI from 2.80 to 2.99). The excessive absolute risk of thyroid cancer, EAR, averaged for the same period is assessed as 6.1 case per 10 4 PYSv (95% CI from 5.8 cases to 6.4 cases per 10 4 PYSv). The averaged excessive relative risk, ERR, is found equal to 22.7/Sv (95% CI from 21.5 to 23.9/Sv) and the averaged attributive risk, AR, is estimated equal to 65.4% (95% CI from 62.1 to 68.8%).
