A research on double peak phenomena of nuclide migration in loess media of unsaturated zone
In order to study the mechanism of double peaks at nuclide migration in unsaturated zone
theoretical analysis and calculations were carried out. The results indicated that ion exchange processes did not cause the double peak phenomena. The field experiments in unsaturated zone were also conducted by using the stable isotope tracers of Sr
Nd and Ce. The results verified such doubles peaks might be caused by the difference of K d between the source and loess layers.
