摘要：

The current status of C-14 measurements at the University of Arizona accelerator mass spectrometry (AMS) facility are summarized. New developments in measurements of in situ produced C-14 by the spallation of oxygen by cosmic-ray neutrons in terrestrial rocks are also discussed. These results indicate that spallogenic C-14 can be measured in high-altitude rock samples, and that the measured production rates agree well with theoretical estimates.
