The metal surface exposed to uranium hexafle uoride corrodes covering radioactive materials.
We studied reasonably decontamination method. In this test, decontamination characteristics using functional electrolyzed water were evaluated using a sample.As a result, it was confirmed that the corrosion layer and the base material surface after releasing to the atmosphere that the radioactive substance remained can be effectively removed.
