Thyroid Cancer Incidence Among Population Who Lived Close to Acting Atomic Facility in Childhood

Necessity of cancer incidence studies among the residents of Ozyorsk, as the nearest settlement to Mayak PA, is supported by the fact that uncontrolled gas-aerosol emissions mainly 131I to the atmosphere took place in the initial years (1948-1962) of operation of the enterprise.

In the cohort of persons residing as children in Ozyorsk in that period, age- and sex-related thyroid cancer incidence rates and relative risk of thyroid cancer incidence in men and women significantly (2–3 times) exceeded those in the national and regional statistics. The correlation between dose and effect was not observed. It could be associated with using group doses due to lack of individual doses. Also we found practically two fold increase of thyroid cancer risk for “rural” individuals compared to “urban” residents associated with dietary patterns, which were likely to cause an increased intake of radioactive iodine.
