Determination of Calcium, Phosphorus, and the Calcium/Phosphorus Ratio in Cortical Bone from the Human Femoral Neck by Neutron Activation Analysis Article in Applied Radiation and Isotopes 56(6.   An approach to the problem of bone disorders is the measurement of the skeletons’ static and dynamic strength, an estimate of the bone mineral density. A decrease in the bone density may be due to the decrease in either Ca or P content, or to dissimilar decreases in both. Consequently, the determination of the Ca/P ratio may provide a sensitive measure of Cited by: 2.   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” A re: Ca=±10 mg/g, P=±5 mg/g and F±20μg/g. The accuracy for all three elements is≤4%, precision being about 3%. The limit of determination for F is μg, for Ca 30 mg and Cited by: 5. 1. J Nucl Med.

Since bone is a biomaterial that is structurally adapted to. Body sodium (Na), calcium (Ca), and chloride (Cl) of guinea pigs weighing between and g were measured by total body neutron activation analysis (TBNAA) followed by chemical analysis (CA) on animals. Paired t test was used to compare any differences in the results obtained by the two : H. P. Sheng, R. A. Huggins, C. Garza, H. J. Evans, A. D. LeBlanc, B. L. Nichols, P. C. Johnson.   The aim of the present study was to determine the effect of calcium phosphate and/or vitamin D3 on bone and mineral metabolism. Sixty omnivorous healthy subjects participated in the double-blind, placebo-controlled parallel designed study. Supplements were tricalcium phosphate (CaP) and cholecalciferol (vitamin D3). At the beginning of the study .
