摘要：
Accelerator mass spectrometry measurements of long-lived radioisotopes, e.g. Be-10, Cl-36 and I-129, of interest in geoscience and other fields have been performed at the China Institute of Atomic Energy. The sensitivity for Cl-36/Cl is 10(-15) and the background for I-129 Corresponds to a I-129/I-127 ratio of 10(-11) to 10(-12). Measurements have been carried out on samples of manganese nodules and deep-sea sediments for Be-10; of ground water, halites and uranium ores for Cl-36; and of uranium ore and groundwater in a uranium deposit area and seaweeds for I-129.
