Dust Deposition and Its Measurement by 137Cs in The Gonghe Basin, Qinghai Province, China
青海共和盆地降尘观测与137Cs测定的初步结果

Through the dust observation at three sites in the Gonghe Basin, Qinghai Province, China and 137Cs analysis of dust samples, the 137Cs technique is firstly used to study the dust deposition by storm. The rate of dust deposition and its monthly distribution were determined and the dust source traced by 137Cs. It is apparent that the 137Cs model for accumulation rate must be modified because of the 137Cs redistribution from dust gain. These tentative results may be have some significant implications for further dust storm research.
