METHOD FOR DECONTAMINATING SURFACES, WHICH HAVE BEEN CONTAMINATED WITH ALPHA EMITTERS, OF NUCLEAR PLANTS

摘要

The invention relates to a method for decontaminating surfaces, which have been contaminated with alpha emitters, of nuclear plants, which method is carried out subsequently to a decontamination process which is aimed at the removal of oxide layers. The surfaces are treated with an aqueous solution which contains a cationic or zwitterionic surfactant and oxalic acid, wherein at least a part of the solution, after having acted on a surface, is conducted across an ion exchanger.
