Vertical migration of fallout super(137)Cs in agricultural soils from Southern Chile
Total inventories and depth distributions of atomic weapons testing fallout super(137)Cs were determined at four sites in Chile. Cesium inventories are always higher than previously estimated for the Southern Hemisphere and depend on annual rainfall. From the measured depth distributions cesium migr...

Summary: | Total inventories and depth distributions of atomic weapons testing fallout super(137)Cs were determined at four sites in Chile. Cesium inventories are always higher than previously estimated for the Southern Hemisphere and depend on annual rainfall. From the measured depth distributions cesium migration rates of <0.5 cm/year were calculated. Modeling the super(137)Cs transport by the convection-dispersion equation yielded a better accordance with the measured depth distributions than the application of a compartmental model. |
