采用火焰原子吸收光谱法测定放射性作业人员血清中铜、铁、锌，并和无射线接触史对照人群作对照；测得结果经统计学检验表明两组人群血清中铜、锌含量有显著性差异，血清铜、锌含量在放射人员中存在着性别差异，放射作业人员中锌含量与工龄呈负相关，而且本研究提示：长期从事放射性作业可以导致体内微量元素铜、锌明显降低。血清铁在本次研究中均未发现性别与工龄差异，其原因有待进一步研究。
Flame atomic absorption spectrometry was used to determine the serum copper, iron and zinc of radioactive workers and compared with the non-radiation exposure history control group. The results of the test showed that there was significant difference in serum copper and zinc content between the two groups There was a gender difference in serum copper and zinc content among radiation workers. The zinc content in radiation workers was negatively correlated with the length of service. And this study suggests that long-term radiological work can lead to significant decrease of trace elements copper and zinc in the body. Serum iron in this study did not find differences in gender and length of service, the reasons for further study.
