Abstract
Many generations (1-18) of natural populations of small mammals that inhabited in 1986-1991 areas contaminated by radionuclides, had increased levels of the mutations in somatic cells and gametes. The high frequency of chromosome aberrations in somatic cells of young carps from contaminated ponds was detected in 1988-1992. Radiosensitivity of hereditary structures of animal somatic cells and gametes was increased in subsequent generations as compared with generations that lived in 1986-1988.
摘要
1986年至1991年期间栖息在受放射性核素污染地区的小型哺乳动物自然种群的许多代（1至18代），其体细胞和配子中的突变水平有所增加。1988年至1992年期间，在受污染池塘的幼鲤体细胞中检测到了高频率的染色体畸变。与1986年至1988年生活的世代相比，动物体细胞和配子的遗传结构在后代中的辐射敏感性有所增加。
