The frequencies of translocations and dicentrics detected by "chromosome painting" in lymphocytes were estimated in 115 healthy donors and in 273 people exposed to uncontrolled irradiation at low doses 1-4 years ago. Age responses of both types of exchanges at the age range from 3 to 85 years fit to quadratic model. The frequency of translocations grew faster with age than the frequency of dicentrics. The yields of stable exchanges in exposed people was significantly higher than those in control donors of corresponding ages.
通过“染色体描绘”检测淋巴细胞中易位和双着丝粒的频率，在115名健康供者以及273名在1 - 4年前受到低剂量无控制照射的人群中进行了估算。在3至85岁年龄范围内，这两种类型交换的年龄反应均符合二次模型。易位频率随年龄增长的速度比双着丝粒频率更快。受照射人群中稳定交换的发生率显著高于相应年龄的对照供者。
