Abstract
The frequency of micronuclei was estimated in bone marrow polychromatic erythrocytes (PCEs) of mice gamma-irradiated in vivo at doses of 5-50 cGy. The dose-effect curve was found to have a complex stepwise pattern with three consequent segments: (1) high radiosensitivity, (2) a significant decrease in radiosensitivity, and (3) an increase in radiosensitivity.
摘要
对体内接受5 - 50 cGy剂量γ射线照射的小鼠骨髓嗜多染红细胞（PCEs）中的微核频率进行了估计。发现剂量效应曲线具有复杂的逐步模式，由三个连续的部分组成：（1）高放射敏感性，（2）放射敏感性显著降低，以及（3）放射敏感性增加。
