On the assumption that the potassium content of the lean body mass is constant, it should be possible to estimate fat content in living man from a measurement of potassium-40 activity in the whole-body scintillation counter. A series of such measurements on children and young adults shows good correlations with skin-fold thickness and weight/height ratio as indices of fatness.
假设去脂体重中的钾含量恒定,那么通过全身闪烁计数器测量钾-40活度,应该能够估算出活体中的脂肪含量。对儿童和年轻人进行的一系列此类测量显示,与作为肥胖指标的皮褶厚度和体重/身高比具有良好的相关性。
