Description

Distribution coefficients of strontium, cesium, uranium, plutonium and americium on pulverized mortars and aggregates were measured to estimate infiltration of such radionuclides in concretes using a model. The model was constructed based on partition equilibrium. Depth profiles for the nuclides in columns experiments were compared with that estimated with the model. Both depth profiles agree with each other. In addition, we estimated the depth profiles for the nuclides in concrete. According to the model, the atoms of Sr infiltrate much deeply in mortar than the other nuclides. (author)
