【摘要】 通过对土壤放射性调查可以掌握土壤中放射性元素的分布,也可以为环境放射性影响评价提供依据。这些工作对于城市而言,可以保障人们的生活和环境安全。而对于核设施则帮助制定退役、去污策略,以防止放射性污染物向环境迁移,危害环境安全。综述土壤放射性污染水平监测方法,其中取样方法涉及了取样工具要求、分层采样的方法。污染物分析监测方法则具体阐述了用中子活化分析方法研究土壤中的微量元素含量、如何监测土壤特性的方法。更多还原

【Abstract】 Radioactivity level survey of soil not only helps to obtain information about distribution of radio-elements,but also supplies foundation for environmental assessment of radioactivity.Radioactivity level survey of soil can assure safety for urban people and environment.Meanwhile,it can help to determine strategy for decommissioning and decontamination,so that the proper measurement can be taken to prevent radioactive pollution moving to environment.In the paper,that review survey of radioactivity level of soil is reported and some of sampling methods,requirement of sampling tools are described.In part of analysis and monitoring method,how to use neutron activation analysis method to study microelement in soil and how to characterize properties of soil is described in detail.更多还原
