Internal doses to Ukrainian populations using Dnieper River water
The dynamics of internal doses from {sup 137}Cs and {sup 90}Sr as a consequence of the use of Dnieper River water were calculated. Local peculiarities of municipal tap, irrigation, and fish consumption in the Ukraine were considered. The dynamics of {sup 90}Sr accumulation in human bone as a result of the use of Dnieper water is simulated. The dose predictions are based on de facto data and the stochastic forecast of radionuclide concentrations in Dnieper reservoirs. A large array of statistical data on the age-structures of exposed populations, food consumption rate, agricultural production, fish contamination, and site-specific parameters were used. Exposures are estimated for 12 regions of the Dnieper basin and the Crimea Republic. The maximal individual annual committed effective doses are 1.7 x 10{sup {minus}5} and 2.7 x 10{sup {minus}5} Sv from {sup 90}Sr and {sup 137}Cs, respectively, due to the use of water in 1986 by members of the population in the Kievska region. Commercial fishermen on the Kievska reservoir, who consumed 360 kg y{sup {minus}1} of fish in 1986, received 4.7 x 10{sup {minus}4} and 5 x 10{sup {minus}3} Sv from {sup 90}Sr and {sup 137}Cs, respectively. The contributions to the collective (over 70 6) effective dose of irrigation, municipal tap water, and fish consumption for members of the general public, respectively, are 18%, 43%,39% in the Kievska region; 8%,25%,67% in the Poltavska region; 50% 50%, 0% (no Dnieper fish consumed) in the Crimea Republic. The predicted contribution of {sup 90}Sr to collective dose resulting from the use of water is 80%. The collective dose to the population of the Dnieper regions (32.5 million people) is 3,000 person-Sv, due to the use of water. 14 refs., 12 figs., 2 tabs.
