~(125)I 是医疗中已广泛用于人体的重要放射性核素。由于它衰变放射出γ射线,尤其是放出俄歇电子,所以人们对其细胞遗传效应非常重视。为此,作者以瑞士小白鼠为对象,以骨髓红细胞微核及头部畸形精子为指标,详细观察分析了~(125)I 诱发的细胞突变潜能。本文以8～9周龄、体重20～23克雌鼠观察微核。以9～10周龄、体重21～23克雄鼠进行头部畸形 ~ (125) I is an important radionuclide that has been used clinically in the human body. Because of its decay radiation γ rays, in particular the release of Auger electrons, so people attach great importance to their cytogenetic effect. To this end, the author of Swiss mice as the object to the bone marrow erythrocyte micronucleus and head abnormalities sperm as an indicator, a detailed observation and analysis of ~ (125) I-induced cell mutation potential. In this paper, 8 to 9 weeks old, weighing 20 to 23 grams of female mice observed micronuclei. 9 to 10 weeks old, weighing 21 to 23 grams of male mice for head deformities
