Abstract (en)

[origin: DE19818772A1] The invention relates to a method for reducing the level of radioactivity of a metal part. To this end, an oxide layer is firstly removed from the metal part by using a decontamination solution. Afterwards, an oxidizing agent which is still present is removed from the decontamination solution. As a result, a layer of the metal is removed. The remaining metal can be delivered to a common scrap yard since radionuclides are only found in the layer of the metal part located close to the surface.
