【摘要】 用4～6周龄的苏州三元白猪活体进行皮肤去污实验。用SM系列去污剂按标准程序对液体放射性沾染进行即刻去污,结果为:对¹³¹Ⅰ的去污效率K=97.7％（去污因子DF=43.5）;对⁹⁰Sr/⁹⁰Y,MFP及U+TRU的K>99％（DF>100）;对¹³⁷Cs的K=99.9％（DF=1000）。污染滞留3h后对各种核素的DF=27～67（K=96.3％～98.5％）。MFP初始污染强度由20s^-1·cm^-2增至300s^-1·cm^-2,即刻去污的DF值由20增至173,去污后残留活度一般不大于10Bq·cm^-2,不需作进一步的去污处理。对放射性尘埃造成的皮肤沾染,滞留4h后DF=57～1000（K=98.2％～99.9％）。SM系列去污剂为中性液体或膏剂,对皮肤无刺激作用。用于核工业正常运行及事故情况下人员的皮肤去污,操作简便快捷,可望获得满意的去污效果。更多还原

【Abstract】 Living 4-6 week-aged San Yuan white pigs (Suzhou, China) were used in skin decontamination experiments. Following a standard procedure, SM series of decontamination agents were used for decontamination of liquid nuclides. The results of immediate decontamination were as follows: K(decontamination efficiency) = 97. 7% (decontamination factor DF = 43. 5) for 131I; K >99% (DF>100) for 90Sr/90Y, MFP and U+TRU; K =99. 9% (DF = 1000) for 137Cs. In 3 h-delayed decontamination,DF = 27-67 ( K =96. 3%-98. 5%) for the nuclides mentioned above. When the initiatory MFP contamination increased from 20 to 300 s-1 . cm-2, the value of DF by immediate decontamination increased from 20 to 173 with the remaining activity not higher than 10 Bq . cm-2, and no additional decontamination was needed. For radioactive ash contamination of skin, DF=57-1000 ( K =:98. 2%-99. 9%) in 4 h-delayed decontamination. SM series of decontamination agents are neutral liquid or cream without any irritative effect on skin. They are effective and easy to use in skin decontamination.更多还原
