Abstract: In the current work improved (more accurate) methodology of evaluating dose on the thyroid gland is introduced, by the help of direct radiometry developed in the Medical Radiological Research Centre of the Russian Academy of Medical Sciences. Data on low-contaminated areas of the Kaluzhsk region is available. Evaluation of radiation risks for thyroid cancer, for the cohort exposed in its childhood in 1986 (2005 people), is implemented. In children, aged 2-4 at that time, who lived in the Ulyanovsk, Khvatovichsk and Zhindrinsk districts, severe radiation risk for the thyroid gland is detected (ERR/Гр=7,14, p<0,025). Children, aged 5-10, from the same region, show important risk for aggregate of the cysts of the thyroid gland and its nodal diseases (ERR/Гр=12,02, p<0,05). In the examined cohort, the probability of radiation factors being the cause of the current diseases is not less than 23 %.
