A method for treating waste gases containing radioactive contamination, particularly krypton and xenon nuclides. The waste gas stream to be decontaminated is initially conducted through an enrichment system wherein the waste gas stream is divided into at least two partial streams one of which is substantially free from the radioactive impurities and constitutes the poor gas fraction and another of which constitutes the rich gas fraction. The poor gas fraction is discharged, at least in part into the atmosphere while the rich gas fraction is fed into an activated carbon delay path whose output is discharged, either directly or indirectly into the atmosphere. Apparatus for carrying out the method is also disclosed. |
