چکیده انگلیسی
Long-lived radionuclides with half-lives ranging from 103 to 108â¯years 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 on 14C, 10Be, 26Al and 129I 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.
