摘要：

Our standard setup used for accelerator mass spectrometry (AMS) with C-14 was modified for measuring various other radionuclides. The injection and detection systems were modified to suit the particular isotope investigated. B-10, the stable isobar of Be-10, is stopped in a gas absorber in front of a surface barrier detector. Al-26 is measured similar to C-14, except for a modification of the timing for the sequential isotope injection. For I-129, a time-of-flight setup was built to separate I-129 from I-127 For heavier rare radionuclides, the mass resolution of the injector system was improved. We also improved our capabilities in measuring carbon samples having very low mass. We describe two different methods to prepare and to measure sub-milligram C-14 samples.
