A simple formula to predict approximate initial contamination of lake water following a pulse deposition of radionuclide.
The objective of this note is to suggest a simple approximate mathematical formula to predict the initial contamination of lakes following a single pulse of radionuclide deposition on the lake water surface. To estimate the initial concentration of 137Cs in lake water averaged over a period of few weeks, the following expression was suggested: Cw = D/(h+h delta), where D is the radionuclide deposition, h is the average depth of the lake and hD is a parameter depending on the sediment characteristics. Using a generic value of h delta = 6 m, the above formula was successfully applied to some European lakes contaminated following the Chernobyl accident.
