SEOUL NATIONAL UNIVERSITY ACCELERATOR MASS SPECTROMETRY (SNU-AMS) RADIOCARBON DATE LIST II

Abstract

The accelerator mass spectrometry facility at Seoul National University (SNU-AMS) began functioning

in December 1998 and was first reported at the Vienna AMS conference in October 1999

and at the 17th Radiocarbon Conference in Israel in June 2000. At the Vienna conference, we

reported our accelerator system (Kim et al. 2000) and the basic sample preparation system (Lee et

al. 2000), including the combustion line to produce CO2; the catalytic reduction line for the graphitization

of CO2; and also pretreatment procedures for wood, charcoal, and peat samples. Recent

progress of the AMS facility (Kim et al. 2001) and extension of the sample pretreatment system to

iron and bone samples were reported at the 17th Radiocarbon Conference (Cheoun et al. 2001). In

the meantime, extensive testing of accuracy and reproducibility has been carried out, and ~1000

unknown archaeological and geological samples have been measured every year. A report of data

carried out in 1999 is presented by Kim et al. (this issue). In this report, the archaeological, geological,

and environmental data carried out in 2000 are presented in terms of yr BP.
