Abstract
The adsorption kinetics of 85 Sr onto three pedologically characterized mineral soils was investigated, namely, one soil from the Chernobyl-Exclusion zone, Ukraine (CEZ-soil), one soil from the dismantling site of a former nuclear research reactor in Germany (DRE-soil) and a sandy reference soil (RefeSol-04A) from the Fraunhofer IME system, Germany. After seven days of treatment with 85 Sr on an overhead shaker, Sr-sorption reached a (temporal) steady state. This timeframe was consistent for all three soils and independent of soil characteristics. From this experiment, maximum K d values were calculated and compared with the existing literature. They agreed well with predictions made by the co-criterion concept for K d (Sr) proposed by IAEA. Furthermore, the effect of gamma-sterilization and the consistency of K d values in soils over longer periods of time is discussed.
