ABSTRACT:
A method for recycling metal parts contaminated by radioactive elements, in particular by .alpha.-emitters, includes forming a melt and a slag from the metal parts and then separating the slag from the melt. The radioactive elements are oxidized prior to the formation of the melt and the slag. For that purpose, the contaminated metal parts are exposed to an oxygen-containing atmosphere for a period at a temperature below the melting temperature of the metal parts.
