Radioactive contamination of water ecosystems and sources of drinking water

The contribution of aqueous components to the individual and collective doses received by the population as a result of the accident at Chernobyl in 1986 did not exceed 1-2%. In the first few days after the accident, the total beta radioactivity of the water was 1x10-7 Ci/L. Subsequently, the concentration of radionuclides in the water fell steadily and throughout 1987 was stable at 1-3x10-10 Ci/L. The highest recorded figure was 4x10-9 Ci/L in May 1986 caused by iodine-131 (for the Dnepr). (author). 1 fig.
