Method for the radioactive decontamination of soil by dispersed air flotation foam and said foam

The present invention relates to a process for treating an earth contaminated by at least one radionuclide such as cesium 137Cs comprising at least one step of separating said radionuclide by dispersed air flotation foam produced by blowing air bubbles in a suspension comprising said earth and at le...

Beschreibung
Zusammenfassung:	The present invention relates to a process for treating an earth contaminated by at least one radionuclide such as cesium 137Cs comprising at least one step of separating said radionuclide by dispersed air flotation foam produced by blowing air bubbles in a suspension comprising said earth and at least one collector. The present invention also relates to the flotation foam obtained by implementing such a process.
