The International Atomic Energy Agency (IAEA) coordinates the work of a world-wide network of analytical laboratories, the Analytical Laboratories for the Measurement of Environmental Radioactivity (ALMERA) network. A proficiency test for ALMERA members was organized in 2006 based on the determination of gamma-emitting radionuclides ((54)Mn, (60)Co, (65)Zn, (109)Cd, (134)Cs, (137)Cs, (241)Am and (210)Pb) in three matrices: water, soil and grass. This paper presents the methodology applied in this proficiency test and discusses the results of the analytical performance evaluation for 38 participating laboratories. The paper also addresses some technical root causes, which could explain low performances in the determination of (109)Cd and (210)Pb.
国际原子能机构（IAEA）协调着一个全球分析实验室网络——环境放射性测量分析实验室（ALMERA）网络的工作。2006年，基于对水、土壤和草三种基质中发射伽马射线的放射性核素（（54）锰、（60）钴、（65）锌、（109）镉、（134）铯、（137）铯、（241）镅和（210）铅）的测定，为ALMERA成员组织了一次能力验证测试。本文介绍了此次能力验证测试中应用的方法，并讨论了38个参与实验室的分析性能评估结果。本文还探讨了一些技术根源，这些根源可以解释在（109）镉和（210）铅测定中表现不佳的原因。
