Factors governing strontium-90 export with surface runoff in the Chernobyl NPP restricted zone

Statistical analysis of collected data revealed priority factors affecting radionuclide migration in water. Considerable changes in the coefficients of correlations between the many-year values of those factors and the water export of 90 Sr make it possible to identify the stages associated with a m...

Zusammenfassung:	Statistical analysis of collected data revealed priority factors affecting radionuclide migration in water. Considerable changes in the coefficients of correlations between the many-year values of those factors and the water export of 90 Sr make it possible to identify the stages associated with a mass passage of primary 90 Sr inputs into water-soluble forms. The landscape characteristics of drainage basins were used to construct regression forecast models of the export of pollutants from watersheds.
