摘要:
We summarize how radiocarbon measurements are made using accelerator mass spectrometry. We also discuss some complications inherent in the radiocarbon-dating method when calibrating radiocarbon dates to calendar dates. For example, measurements of radiocarbon (C-14) in some types of materials are complicated by a "reservoir effect", caused by an apparent age of the source reservoir that differs from the contemporary atmospheric surface C-14 value. In other cases, mobile carbon sources in nature can produce mixed sources of carbon. We explore these effects and discuss their possible implications for C-14 measurements and how we can deal with them. (C) 2012 Elsevier Ltd and INQUA. All rights reserved.
