In 95 healthy subjects of either sex the serum concentrations of Cu, Au, and Mn were determined by means of neutron activation analysis (NAA). It was found that copper concentration in the serum of healthy subjects increased with age up to 70 years of life. In subjects aged below 60 years a higher gold level was demonstrated in the serum than in the subjects aged above 60 years. Serum manganese level was higher in men than in women.
采用中子活化分析法（NAA）测定了95名不同性别的健康受试者血清中铜、金和锰的浓度。结果发现，健康受试者血清中的铜浓度随年龄增长至70岁而升高。在60岁以下的受试者中，血清中的金含量高于60岁以上的受试者。男性血清锰水平高于女性。
