Abstract: The wiping decontamination and stripping coating decontamination were applied to decontaminate the floors and metals in the glove box polluted by tritium. The results show that the polluting level is lower than 20 Bq/cm2 through wiping decontamination. The DFs are higher for decontaminating higher-polluted metals using two stripping coatings while the polluted-level is lower than 20 Bq/cm2 for decontaminating lower-polluted metals.
