| 摘 要： | Loess is the most important and the most typical continental classic sediments of Quaternary. So the measurement of In-situ produced cosmogenic 10Be is expected to be used for the Loess stratigraphic age. But the production rate of In-situ produced cosmogenic 10Be in Loess quartz is very low. It requires very high sensitivity and accuracy of measurement. This work has measured the concentrations of 10Be of two layers in Loess section of Luochuan including L8, L9 and the concentrations of 10Be in (of) blank sample with the HI-13 AMS system at China Insitute of Atomic Energy(CIAE), then calculated the content of 10Be in loess quartz for each layer. The ratio of 10Be/9Be was found in the range of 10－13. The background of 10Be/9Be was about 3×10－14.
