摘　　要：36Cl, the long-lived radioactive nuclide, exists abroadly in atmosphere and lithosphere. Erosions and exposure ages of rocks can be determined by measuring 36Cl concentration in rocks. In recent years, accelerator mass spectrometry (AMS) is the only effective tool to measure 36Cl. In the present work, the method of 36Cl measurement with AMS was researched, and the erosion rate of limestone at Shihuadong region of Beijing City was calculated with the method, the result obtained is (1.33±0.28)×10-5 m·a-1.
