摘要：

Accelerator mass spectrometry is so sensitive to small quantities of Ca-41 that it might be used as a tracer in the study of human calcium kinetics to generate unique kinds of data. In contrast with the use of other Ca isotopic tracers, Ca-41 tracer can be so administered that the tracer movements between the various body pools achieve a quasi steady state, Resorbing bone may thus be directly measured, We have tested such a protocol against a conventional stable isotope experiment with good agreement.
