The migration and distribution of radionuclides (60Co, 85Sr and 137Cs) in an aerated sand layer are examined with a sand layer model apparatus. The adsorption ratio of each radionuclide in the sand layer decreases exponentially in the upper part, and more slowly with increase in the depth of the sand layer. Distribution of 137Cs in the vertical cross section is such that its migration is uniform within the whole section, while that of 60Co is such that the migration is larger in the center than in the perimeter. Distribution of 85Sr shows intermediate character between that of 137Cs and 60Co. Those distributions observed are compared with calculated ones on the basis of the dispersion equation, and it is found that the agreement is relatively good only for 85Sr. For 85Sr, the migration in the aerated sand layer can be practically estimated with the dispersion equation.
