N2 - We are investigating long- and short-term processes that involve the resorption of the bone calcium in the human body, using accelerator mass spectrometry of 41Ca (T 1 2 = 104000 years). The evolution of an injected dose of 41Ca has been followed over 900 days by measurements in urine and serum. The 41 Ca/Ca isotopic ratio rapidly decreased after injection and after about 100 days, reached a quasi-steady state of 1.5 × 10-11. Variations in this level would signal a change in rates of calcium resorption from the bone.
