古代人骨的加速器质谱计 ^(14)C 测量

AMS measurements of 14C for human bone fossils

利用北京大学加速器质谱装置成功地测定了一批用其它方法难以断代的古人类骨化石的年代。对现代样品的１４Ｃ测量精度可达１％，样品测量本底不大于０．００６ＭＣ。

? Since the establishment of Peking University Accelerator Mass Spectrometry (PKUAMS), a series of successful application research have been made in various fields More than 20 human bone fossil samples in unknown layers from different areas of China have been measured by the PKUAMS facility The facility and 14C measurements are described in detail in this paper
