The paper discusses a methodological approach developed for reconstruction of thyroid doses from internal exposure to I-131 and prospects of future works in this field. Estimated levels of thyroid irradiation for the population of Russia after the accident are presented. These results have been obtained based on the retrospective analysis using the developed approach. Also, longterm health consequences of thyroid irradiation in the population of Russia have been predicted. Retrospective estimates have been made for individual thyroid doses for children and adolescents with the diagnosis of thyroid cancer living on the contaminated areas.
