Abstract
The kinetics of radiocesium sorption and desorption by cation solution s and the corresponding radiocesium distribution profiles in sediment cores were investigated. The results have shown that a significant per centage of radiocesium is adsorbed in the sediments during the first 3 d. Radiocesium reaches rapidly (< than 5 d) at a depth which does not exceed 3.5 cm. The desorption of radiocesium was found to depend on c ation concentrations. Empirical laws are derived bath for cesium adsor ption and desorption.
