本文叙述了拆除两个钚沾污手套箱的辐射防护工作。手套箱经去污后,估计还残留有1.2毫居里的α放射性。采用喷漆复盖污染面的方法等安全防护措施后,在前区进行拆卸。现场监测结果表明,空气中α放射性气溶胶浓度最大值为1.1×10~(-15)居里/升,很少发现有表面污染现象。 This article describes the radiation protection work to remove two plutonium-contaminated glove boxes. After the glove box has been decontaminated, an estimated 1.2 millicuries of alpha radioactivity remains. After using the method of spraying paint cover pollution surface and other safety precautions, disassemble in the front area. The field monitoring results showed that the maximum concentration of alpha radioactive aerosols in the air was 1.1 × 10 ~ (-15) Curie / liter, and few surface contamination was found.
