SUMMARY With the use of Ca 47 , the exchangeable calcium (E) and the accretion of calcium to bone (A) have been estimated in 15 subjects—four normal, five osteoporotic, one chronically immobilized, three acutely immobilized, and two receiving prednisolone for active arthritis. Low values for exchangeable calcium and calcium accretion were found in one normal subject, two osteoporotic subjects and the chronically immobilized subject. High accretion rates were found in one acutely immobilized subject and in both subjects with arthritis. The low values in some osteoporotic subjects and the normal values in others are consistent with published reports, and suggest either that calcium kinetics are not greatly disturbed in osteoporosis, or that this method lacks sensitivity. Some of the problems in the interpretation of radiocalcium data are discussed.
