摘要

介绍了近年来国内外用加速器质谱计在环境科学方面的研究工作

包括测量城市空气污染、监测来自核设施的泄漏和有关全球环境变化的测定。为了适应多学科应用研究的需要

经过对装置进行大规模的改造和对高精度14 C测年方法的研究

北京大学加速器质谱计14 C测量精度已经达到好于 0 .5 %的水平。在国家重大项目“夏商周断代工程”中

测定了大量样品并结合考古信息给出了比较可靠的年表

Abstract

Some important work worldwide in environmental science

like urban air pollution

discharges of radioactive wastes from nuclear plants

and global climate change were introduced. Based on the improvements of facility and studies on 14 C dating method

a precision better than 0.5 % has been reached for the PKUAMS. A large number of samples have been measured for the Xia-Shang-Zhou Chronology project. 14 C data of PKUAMS have made important contributions to creation of more reliable chronological table of Xia

Shang and Zhou dynasties. The improvements of PKUAMS are of benefit to the applications in environmental science in the future.
