Characterisitics of Radioactive Contaminated Soil and Its Decontamination Technology
-
摘要: 放射性污染场地对公众安全和环境的潜在危害很大,其清理往往涉及巨大数量的污染岩土,技术困难和经济代价都很大。去污就是减少污土体积的重要办法之一。讨论了钚受化学爆炸作用分散于土中的深度分布、粒度分布和放射性分布以及钚与土共存的形态特征。介绍了放射性分选、湿法筛分快速分选、选矿分选等最主要的钚分离方法,提出了某场区内污染严重场地去污的基本策略:"减容为主、回收为辅,简便高效、安全经济"。还建议了土壤去污的工程方案。Abstract: The characteristics of depth distribution,particle size distribution,radioactivity distribution,and pollutant-soil co-existing forms is discussed.Some separating methods are introduced and a special engineering decontamination procedure is advanced for site.
