METHOD OF DECONTAMINATING RADIOACTIVE SUBSTANCE

摘要

PROBLEM TO BE SOLVED: To decontaminate metal contaminated with a radioactive substance in a short time. SOLUTION: A decontaminant solution added with hydrogen peroxide to an aqueous organic acid solution is used when a base material of the contaminated metal contaminated with the radioactive substance is dissolved to remove contamination, by the aqueous organic solution. The radioactive substance is removed since the base material of the contaminated metal is dissolved when the decontaminant solution is made to contact with the contaminated metal.
