Method for decontaminating metals contaminated with radioactive substances.

摘要

The present invention provides a method for decontaminating metal components (5) which have been contaminated on their surfaces with radioactive substances, characterized in that radioactivated oxide films (6) on the metal surfaces are electrolytically removed by an alternating electrolysis method in a neutral salt solution (3). According to the invention, oxides and hydroxides of metals removed by the electrolytic treatment are separated from the electrolyte (3) and solidified. The method of this invention makes it possible to positively remove the radioactivated oxide films (6) from a base metal (5).
