Cellular alterations of cultured 3T3 cells irradiated with beta-rays from tritiated water were studied by scanning and transmission electron microscopy. We observed decreased negative surface charges, vacuolization of rough endoplasmic reticulum and Golgi-complex, degeneration of mitochondria, increase of lysosomal activity and changes in distribution and amount of microfilaments in the irradiated cells, that parallelled changes in cell shape.
用氚水的β射线照射培养的3T3细胞，通过扫描电子显微镜和透射电子显微镜研究其细胞变化。我们观察到受照射细胞的表面负电荷减少、粗面内质网和高尔基体空泡化、线粒体退化、溶酶体活性增加以及微丝的分布和数量发生变化，这些变化与细胞形态的改变平行。
