摘要
环境样品放射性测量的溯源性是测量质量保证的核心。本文叙述了与环境样品放射性测量溯源性有关的一些问题:简要介绍了溯源性的概念及其演变;总结了本实验室近几年来在环境样品放射性测量中的质量保证工作,涉及标准的传递、参考物质的制备、Ge(Li)谱仪对体源的效率的刻度、以及比对测量等溯源性实践活动。本文还讨论了溯源性的保持,并对今后工作提出了一些建议。
This paper discusses some aspects on radioactivity measu-rement traceability and summarizes the Work on quality assurance ofradioactivity measurements of environmental samples in the laboratory,including transfer of standards, preparation of reference materials, andcalibration of efficiency for volumse sources with Ge(Li) spectrometer.Some practical activities regarding intercamparison of radioactivity measu-rements and other traceability-related activities are also described. Somesugestions relating to performing quality assurance are made in the paper.
