A new method for easily removing of radioactive cesium from muck soil in forests has been developed. Fine particles of bentonite having negative charge and high adsorbing ability for cesium can effectively adsorb radioactive cesium, and then, the bentonite fine particles can aggregate and being trapped by interaction with interpolyelectrolyte complex having positive charge, which enables an easy removal of radioactive cesium from muck soil in forests.
