在正常人血清中 ,各类免疫球蛋白含量常随年龄而变化 ,但在正常成年人血清中是相对稳定的[1] ,电离辐射可以抑制抗体形成 ,使血清免疫球蛋白含量减少[2 ] 。 2 0 0 2年我们对咸阳市12 5名放射工作人员血清免疫球蛋白含量进行了监测 ,现将结果分析如下。1　对象与方法1.1对象　 In normal human serum, the content of various immunoglobulins varies with age but is relatively stable in normal adult serum [1]. Ionizing radiation can inhibit the formation of antibodies and decrease the serum immunoglobulin content [2] . In 2002, we monitored the serum immunoglobulin levels of 125 radiation workers in Xianyang City. The results are as follows. 1 objects and methods 1.1 object
