皮肤放射性沾染去污剂及去污技术研究

Study of Decontamination Technigue on Skin

目的 研究皮肤放射性沾染的去除技术。方法 用苏州三元 4 - 6周龄小白猪 ,新西兰大白兔和新鲜猪肉皮进行皮肤放射性沾染去污技术研究 ,以混合裂变产物 (MFP)为沾染核素 ,随后用SM系列 (去污液SMY和去污胶SMJ)去污剂进行去污沾染试验。结果 对猪和兔皮肤表面液体沾染的去污效率分别为 99%和 95 % ,对尘埃沾染大于 99% ,沾染滞留时间 2h后的去污效率降低约 5 %。结论 SMY去污过程基本不产生放射性废水 ,SMT则可进一步减少固体废物量。SM系列去污剂对皮肤无刺激作用也不会引起毒性反应。

Objective To study the decontamination on skin of radioactive.Methods Suzhou San-Yuan white pigs 4～6 weeks old,New Zedand white rabbits and fresh pigs skin were used in skin decontamination experiments.The mix fission product (MFP) were used as radioactive contamination nuclides.Then the SM series (liguid SMY and glue SMJ) were used decontamination agentsas.Results For the decontamination efficiency for pigs and rabbits,liquid decontamination rate was 99% and respectively,for which ashs contamination was greaterf than 99% and decontamination delayed 2hr the decontamination rate was reduced by ～5%.Condusion During the SMY decontamination process there is no produced radioactive waste water basically,SMJ reduces solid waste.The SSM series of decontamination agents have no stimulating effect and toxicity reaction to skin.
