POTASSIUM-40 CONTENT AS A BASIS FOR THE CALCULATION OF BODY CELL MASS IN MAN.
On the assumption that the potassium content of the body cell mass is constant it should be possible to estimate body cell mass by measuring potassium-40 activity with a whole-body scintillation counter. Relations of body cell mass to weight, lean body mass, and total body water are demonstrated.
