ABSTRACT OF THE DISCLOSURE A reagent solution for dissolving oxidized or non- oxidized radioactively contaminated surfaces from metallic articles, particularly lead, having fluoboric acid at a concentration of less than about 80 percent and at least one oxidation agent. An aqueous solution of fluoboric acid and hydrogen peroxide dissolves sufficient metallic surface material to render the metallic article radioactively decontaminated. One preferred solution is about 5 to about 20 percent fluoboric acid and about 0.5 to about 2.0 percent by volume hydrogen peroxide.
