Abstract
The method of treatment of a mixture of air and at least partially radioactive gases such as xenon and krypton in particular, especially gaseous effluents derived from the reprocessing of irradiated nuclear fuels, comprises a stage of concentration of the rare gases in solution in liquid oxygen by cryogenic distillation of the light gases and especially nitrogen from the liquefied mixture.
