半衰期为103 ~ 108年的长寿命放射性核素在地质年代学和环境示踪研究中有着广泛的应用。保存在各种自然档案中的各种气候，地质和环境记录可以通过使用加速器质谱仪（AMS）测量其浓度来表征。本文重点介绍了西安AMS中心自建立AMS专用装置以来，在14 C、10 Be、26 Al和129 I这两个方面所做的一些有代表性的工作。综述了样品制备方法的改进、新的数学分析方法的发展及相关应用。
Long-lived radionuclides with half-lives ranging from 103to 108years have wide applications in geochronology and environmental tracer studies. A wide range of climatic, geologic, and environmental records preserved in diverse natural archives can be characterized by measuring their concentrations, using accelerator mass spectrometry (AMS). The purpose of this paper is to highlight some representative works on14C,10Be,26Al and129I in these two aspects at the Xi'an AMS Center in the past ten years, since a dedicated AMS facility was established. The improvement of the sample preparation procedures, the development of the new mathematical analysis method and related applications are summarized.
