The invention relates to a process for decontaminating the surface of a metal part contaminated by tritium and an apparatus usable for performing this process. In order to carry out the decontamination, the part to be decontaminated is connected to the negative pole of a direct current generator, at least one portion of the surface of this part is contacted with a mixture incorporating water and an electrolyte, e.g. an aqueous solution of soda or sulphuric acid, or water and solid electrolyte, an electric current is passed between the part and an anode connected to the positive pole of the electric current generator by applying to the part to be decontaminated a current density of 10 to 50 mA.cm-2 for the cathodic hydrogen charging of the part being decontaminated and the replacement by hydrogen of the tritium adsorbed on the surface of this part.
