RESUMO
The paper is devoted to one of the most important aspects of the accident at the Chernobyl Nuclear Power Station: thyroid irradiation in the residents of 8 areas in the Ukrainian SSR and the town of Pripyat, affected with radioactive iodine. Irradiation doses, prognosis of medical effects of the accident, methods and practical measures for the organization of endocrinological monitoring of the affected population were thoroughly considered. The authors proposed a scheme of health care of the population in these areas. They also discussed the structure of data bases for analysis of medico-dosimetric information on "iodine" effects of the accident. The main trends in medico-dosimetric problems of the effects of thyroid irradiation were outlined.
