Abstract

The present invention concerns a method for treating soil contaminated by at least one radionuclide such as caesium Cs comprising at least one step of separating said radionuclide by dispersed air flotation foam produced by injecting air bubbles into a suspension comprising said soil and at least one collector. The present invention also concerns the flotation foam obtained by implementing such a method.
