• For the estimation of the leachability of several important radionuclides from the solidified wastes with cement, some adsorptive behaviours of them in cement milk were studied experimentally. Main results obtained are as follows.Cesium could not be adsorbed at all on any crystalline cement-hydrates in the cement milk. Then high leachability from the solidified can be deduced.A some amount of strontium was incorporated into the cement-hydrates by mixing crystallization in the cement milk. In the solidified, therefore, a larger amount of it is assumed to be distributed in the stable crystal of cement-hydrates.The greater parts of zirconium, cobalt, zinc, and cerium were adsorbed firmly in this order on the cement-hydrates, ruthenium and its nitro complex were less adsorbed, showing no significant difference in their behaviour. These adsorptive characteristics were little changed by the presence of carriers and other salts.
