Doses and risks from the water use received by the population of southwest areas of Bryansk region
In the present work the estimation of risk for the population of southwest areas of Bryansk region exposed to radiation fallout after Chernobyl accident is carried out. The life risk of disease for the population of the specified areas is estimated by a cancer through a dose received from water use. The basic ways of radionuclide receipt in an organism of inhabitants of southwest areas of Bryansk region on a water chain are: an external exposure from polluted flood-land of water body, consumption of water from the sources of the drinking water supply located in the polluted zone, and consumption of fish caught from a local water body. As object of research the population living in area of Lake Kozhanovskoe is accepted. The contribution of radionuclides o f<sup>9</sup> Sr and <sup>137</sup>Cs in a total dose from water use is estimated. Priority sources of risk for the population from water use to which it is necessary to pay special attention at carrying out of protective actions in the specified territories are revealed.
