可剥离膜在放射性洗消中的研究进展

Recent progress of strippable coating in radioactive decontamination

放射性洗消一直是洗消技术研究的难点,传统的高压水冲洗、化学试剂浸泡、喷砂等洗消方法具有破坏性,同时产生大量的二次污染物。综述了近20年来可剥离膜在放射性洗消中的研究进展,重点聚焦改进可剥离膜性能、改进去污效果和新型膜材料这3方面的研究热点。分析已有的研究数据,发现虽然可剥离膜去除松散的放射性表面污染是一种很有效的方法,然而大多数相关研究缺乏标准详细的操作规程和定量的数据来评估或比较实验的有效性。

Radioactive decontamination has been always a challenging task on decontamination technology.The traditional methods of radioactive decontamination such as high-pressure wash,chemical immersion and sand blasting can generate toxic byproducts,and exhibit undesirable aggressiveness on materials.The advances in strippable coatings to radioactive decontamination over the past 20 years was reviewed,focus on the research hotspots of impoving the performance of strippable coatings,impoving the decontamination effect and new strippable coatings liquid.Analysis of existing research data shown that strippable coatings could be a valuable method to control loose surface radioactive contaminations.However,majority of studies lacked standard operating procedures and quantitative data to evaluate or compare the effectiveness.
