摘　　要：对氚污染手套箱内壁及金属采用擦拭去污和可剥离膜去污。擦拭去污后,手套箱内壁残留氚污染水平降低到20Bq/cm2以下。对氚污染水平高处采用SO42-/TiO2固体超强酸掺杂可剥离膜或聚乙烯醇(PVA)可剥离膜去污,去污因子高,而氚污染水平低的金属通过可剥离膜去污后残留氚为20Bq/cm2。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.
