Abstract: Descriptive epidemiological analysis of more than 200 thousands of new cancer cases over 25-year period (1981-2005) among population of the Belgorod and Bryansk Regions affected as a result of the Chernobyl accident was carried out. Age-gender dependencies of population oncopathology development during this period as well as the dynamics the incidence changes in separate nosological units were determined. It was shown that exposure in low dose after the Chernobyl accident led to wavy change of the incidence with the period 5-7 years and that radiation-induced incidence developed in the format of spontaneous one. The role of physiological factors of organism and processes of cell proliferation and differentiation in cancer development are discussed.

Keywords: Chernobyl accident, territory contaminated with radionuclides,  Population, thyroid cancer, incidence of disease, crude incidence rate,   standardized incidence ratio, excess relative risk

Abstract: Joint analysis of thyroid cancer incidence in Bryansk, Kaluga, Oryol and Tula oblasts from 1981 through 2008 was made for the first time. The average size of population of the oblasts in those years was 5.1 million people. According to data of the National Radiation and Epidemiological Registry 9120 thyroid cancer cases were detected for that period. Mean-rayon thyroid doses were used for the analysis. Affected rayons of Bryansk, Kaluga, Oryol and Tula oblasts were arranged into 4 groups in accordance with radiation dose:

Dependence of the incidence level of non-oncologic diseases of the thyroid gland, in the post-natal period, on the time of gestation, in children of the Kaluzhsk region, exposed internally due to incorporation of anthropogenic iodine 131

Keywords: children, incidence, diseases of the thyroid gland, internal exposure, iodine 131, cohort research

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.
