摘要
为充分保证样品分析结果的准确可靠,研究建立了受放射性污染土壤的批量预处理方法,对样品烘干、粉碎、筛分、代表性取祥、分析排序技术等关键步骤进行了限定.通过实际样品的处理分析结果表明,该方法能够有效避免样品间的交叉污染问题,对样品分析结果的准确性和代表性有显著提升,可以应用于受放射性核素污染场地的土壤样品批量预处理工作,对于下一步环境评价、环境整治等工作的开展也是有利的.
In order to ensure the accuracy and reliability of sample analysis,a batch pretreatment method of radioactive contaminated soils was established.The key steps such as sample drying,crushing,screening,representative sampling,analytical sequencing and other key steps were determined.The analysis results of actual samples showed that the method could effectively avoid the cross-contamination between samples and significantly improve the accuracy and representativeness of the sample analysisresults. It could be applied to the batch pretreatment of soil samples contaminated by radionuclides,which was beneficial to the next step of environmental assessment, environmental improvement and so on.
