Abstract

We used cytogenetic analysis in the studies of the biological effects of a radiation factor of natural and artificial origin (under conditions ofthe 30-km exclusion zone ofthe Chernobyl experimental landfills in Ukraine, Belarus and Russia). The studies have been performed on various types of mammals: domestic animals--cows, pigs, horses and rodents--root voles, the Af mouse line, and yellow necked field mouse, bank voles. We found significant changes in the level of MN and chromosomal aberrations in the animals that were exposed to the conditions of chronic low-dose radiation for a long time (bothin the habitat and upon exposure in the Chernobyl zone) regardless of the type of animal and nature of contamination.

[慢性低剂量辐照下哺乳动物体细胞诱变的细胞遗传学指标]。
我们使用细胞遗传学分析来研究自然和人为来源的辐射因素的生物效应(在乌克兰、白俄罗斯和俄罗斯切尔诺贝利实验垃圾填埋场30公里隔离区的条件下)。这些研究是在不同类型的哺乳动物身上进行的:家畜——牛、猪、马和啮齿类动物——根田鼠,阿夫鼠系,黄颈田鼠,银行田鼠。我们发现,长期暴露在慢性低剂量辐射条件下的动物(无论是在栖息地还是在切尔诺贝利地区暴露后),无论动物类型和污染性质如何,MN水平和染色体畸变都发生了显著变化。
