英文摘要	Naturally occurring radionuclides (NORN) such as K-40, Ra-226 and Th-232 from 44 surface sediment samples collected from four desert regions of Chinese were determined to investigate the regional characteristics of the source areas of Asian dust. The radionuclides for 41 surface sediment samples collected from seven sites of the Keum River area in Korea were also determined to compare the regional characteristics with the Chinese desert area. The specific activities (SA) and the specific activity ratios (SAR) of the radionuclides were investigated for distinguishing the source region of Asian dust. The SA of Ra-226 and Th-232 as well as the SAR of Ra-226/K-40 and Th-232/K-40 were found to be useful to characterize source area and tracing Asian dust.
