Recycling of radioactively contaminated metal wasles is very attractive to reduce thc final disposal volumc of the radioactive wastes, thereby maximizing the usage of nahrral rzsuunts and minimizmg the detrimental effects of thz rzdioaclive wastes on the environment. In the recycling process, many complicated processes arc involved. Among those processes the 'surface contamination removal techniques such as physical, chemical and electrochern~calm ethods are the most critical and Ircquently applied in accordance with the contamination characteristics and the chemical compositions of the metal wastes. In this sludy, the sulfuric acid-cerium method and electmchemical methods were applied lu removc the conatiminated suhce. The results showed the surface contaminalion could he lowered to the background levcl by lhasc mclhods.
