Carcinogenic Effects in the Exposed Population in the Southern Urals

In the fifties of the twentieth century, two radiation incidents occurred in the South Urals, Russia (the discharge of liquid radioactive waste into the Techa River in 1949-56 and a thermal explosion in the radioactive waste storage in 1957, which resulted in the formation of the East Urals Radioactive Trace). The consequence of these events was the prolonged exposure of the population living in these territories. In the Urals Research Center for Radiation Medicine in Chelyabinsk, cohorts of the exposed population have been formed, the follow-up period for cancer morbidity and mortality is more than 60 years. Studies show that there is a statistically significant increase in the leukemia risk among the Techa River cohort members and an increase in the risk of mortality and morbidity from solid cancer, depending on the dose in the exposed population. The report presents the results of the analysis of radiogenic risk both in those exposed on the Techa River and on the territory of EURT.
