Abstract: Research of 420 children, living in the south-west of the Kaluzhsk region, during 12 years after prenatal exposure to iodine 131. Cohort method is implemented. A control group of 150 children, from the same region, is also examined for comparison. The incidence in the exposed children, in utero, compared to not exposed ones, was 2.6 times higher. The incidence depends on the time of gestation, at which iodine 131 was incorporated. The highest incidence and relative risks were detected in two subgroups: 1. Prenatal “radiation period”: 4-12th weeks, 2. 16-22th weeks. This radiobiological research shows the increased activity of the thyroid gland, in terms of absorbing radioactive iodine, in certain periods of gestation.

Abstract: The purpose of research is to develop methods and assessment of thyroid doses to the residents of Russia, exposed to radioactive iodine isotopes from the Chernobyl nuclear power plant. Studies of the incidence of thyroid cancer due to the absorbed dose to the thyroid and in the assessment of the risk of additional thyroid cancers caused by radiation. Achieving this goal is based on the results of monitoring of iodine radionuclides in the environment, food, in the human body, which was conducted in May-June 1986.
