PROBLEM TO BE SOLVED: To provide a method for treating soil contaminated by at least one radioactive nuclide, such as cesiumCs.SOLUTION: A process includes at least one step for separating a radioactive nuclide by dispersed air flotation foam. The process includes the following steps. (a) Air foam is injected into a suspension liquid containing soil and at least one collector, and foam is formed by the suspension liquid. (b) At least a portion of the foam is separated from a remaining part of the suspension liquid. The collector is selected among, for example, fatty acid, fatty acid salt and cationic surfactant. |
