Vanadium concentrations have been measured in the serum of 23 healthy subjects by neutron activation analysis, with post-irradiation chemical separation. The values obtained fall in a fairly narrow range (260-1300 ng/L, mean 670 ng/L), which suggests a physiological role for this element. We checked the method by analysis of standard (U.S. National Bureau of Standards) water samples and serum samples supplemented with 48V, and we found excellent agreement with expected results in both cases. We consider the reported results for human serum to be more reliable than those obtained by atomic absorption spectroscopy.
通过中子活化分析并结合辐照后化学分离法，对23名健康受试者的血清钒浓度进行了测定。所得数值落在一个相当窄的范围内（260 - 1300纳克/升，平均670纳克/升），这表明该元素具有生理作用。我们通过分析标准水样（美国国家标准局）以及添加了48V的血清样本对该方法进行了检验，发现两种情况下的结果与预期结果都高度吻合。我们认为所报道的人血清结果比通过原子吸收光谱法获得的结果更可靠。
