INAA of Ca, Cl, K, Mg, Mn, Na, P, and Sr contents in the human cortical and trabecular bone

Summary

Concentration of Ca, Cl, K, Mg, Mn, Na, P, and Sr were determined by instrumental neutron activation analysis using short-lived radionuclides in intact cortical and trabecular bone of femoral neck and iliac crest of 81 relatively healthy 15-55 years old women (n = 36) and men (n = 45). In cortical bone the Ca, P, and Mg mass fractions in the femoral neck were statistically significantly higher, and Cl, K, and Na lower, than the values for the iliac crest. In trabecular bone the Cl, K, and Na mass fractions in the iliac crest were significantly higher, and Ca, P also higher, than the values for the femoral neck.
