放射性环境监测平行样品采集及判定方法研究

Discussion on Collection and Determination for Parallel Samples in Radioactive Environmental Monitoring

放射性环境监测中平行样品是质量保证的一项重要内容,对平行样品的采集过程结合实际进行了探讨,同时对平行样品的标识、交接、测量等过程中的关键因素做了分析,并利用统计学的方法对平行样品的结果进行了判定,认为平行样品采集环节是至关重要的一步,但因其不确定度难以评定,会对平行样品结果的判定造成困难。

The parallel sample is an important part of quality assurance in radioactive environmental monitoring. Combining with practical condition,collection process of parallel samples is discussed in this paper. The key factors in the process of identification,transfer and measurement of parallel samples are analyzed,and the results of parallel samples are determined by statistical method. It is considered that the parallel sample collection is a very important step,however,the uncertainty is difficult to assess,which results in the difficulty in determining the parallel sample result.
