Prediction of runoff transport of fallout 90Sr.
A model is described for the prediction of runoff transfer of fallout 90Sr without recourse to long-term measurements. The values of model parameters can be readily established from few field measurements of the solid/solution partitioning of 90Sr and a natural, atmospherically delivered radionuclide such as 210Pb, and the usually well documented fallout and hydrologic data. The model-generated profiles of 90Sr for two major Canadian watersheds compare favorably to those established through long-term monitoring of receiving waters.
