The determination of fluorine, calcium and phosphorus in bone by instrumental fast neutron activation analysis is described.
Results for the IAEA standard material “Animal Bone” A3-74 re: Ca=313±10 mg/g, P=155±5 mg/g and F-613±20μg/g. The accuracy
for all three elements is≤4%, precision being about 3%. The limit of determination for F is 120 μg, for Ca 30 mg and for P
1 mg in a sample of 500 mg.
