ANALYSIS OF SOLID CANCER MORTALITY RISK FOR THE POPULATION EXPOSED IN THE TERRITORY OF EAST-URALS RADIOACTIVE TRACE OVER A 50-YEAR PERIOD

Abstract

The results are presented of the late health effects assessment for the population of the East-Urals radioactive trace exposed to the long-term influence of external and internal exposure (average dose to stomach accumulated during the whole period of surveillance amounts 0,03 Gy, maximal – 0,69 Gy). For the first time, individualized doses were used in the analyses which were calculated basing on the TRDS-2009 dosimetric system. It has been shown that the risk value per unit dose for solid cancer mortality inChelyabinsksubcohort of East Ural radioactive trace associated with a long-term exposure at low to medium doses is similar to that estimated for cases of acute exposure at high doses. The results are comparable to those obtained for the members of the Techa River Cohort.
