Neutron activation analysis (NAA) for the determination of some trace elements in biological samples is described. This method permits the simple and rapid determination of Se, Hg, Fe, Co, Zn, Ag, Sn, Cr, Yb, Sb, Au and As after a radiochemical separation from Na, Cs, Rb and, partially, Br. For this purpose, precipitation by adding sulphide and hydroxyl ions was used. An attempt was made to simplify the radiochemical procedure. The present (destructive analysis) was tested in radiotracer experiments. Further tests were made using standard biological materials. The method should find applications in neutron activation analysis, particularly of biological materials.
描述了用于测定生物样品中某些微量元素的中子活化分析（NAA）。该方法能够在从钠、铯、铷以及部分溴进行放射化学分离后，简单快速地测定硒、汞、铁、钴、锌、银、锡、铬、镱、锑、金和砷。为此，采用了添加硫化物和氢氧根离子进行沉淀的方法。尝试简化放射化学程序。目前的（破坏性分析）方法在放射性示踪实验中进行了测试。还使用标准生物材料进行了进一步测试。该方法应能在中子活化分析中得到应用，尤其是在生物材料分析方面。
