最近Gyeen等的工作证实:由于内辐照源钚的非均匀分布,而引起对性腺组织的遗传学损伤的潜在性危险。实验选用100天龄的B6CF1雄性小白鼠26只,每只静脉一次注入10微居里/公斤体重的单体~(239)钚一柠檬酸盐。注入后6、30. 75、222、348天处死动物,剖取睾丸,称重。每个时间点再取两只动物的 Recent work by Gyeen et al. Has demonstrated the potential risk of genetic damage to gonadal tissue due to the non-uniform distribution of plutonium within the irradiation source. Twenty-six B6CF1 male mice, 100 days old, were injected with 10 μg / kg body weight of monomer (239) plutonium-citrate once per vein. Animals were sacrificed 6,30. 75,222,348 days after injection, testes were dissected and weighed. Take two more animals at each time point
