Abstract

The dynamics of chromosome aberration frequency in bone marrow cells of many generations (14) of bank vole living in the radioactive trace of the Chernobyl catastrophe (1986-1992) has been analysed. The study revealed that the chromosome aberration frequency in voles in the areas with radio-contamination density 220 and 1526 kBq/m2 (for 137Cs) significantly exceeds the control level 3-7 times over the whole period under investigation. The dynamics of the frequency of structural chromosome injuries from 1986 to 1991-1992 is characterised by the tendency to increase in all populations inhabiting the areas with various radio-contamination density (8-1526 kBq/m2).

摘要

对生活在切尔诺贝利灾难(1986 - 1992年)放射性痕迹中的多代(14代)田鼠骨髓细胞中的染色体畸变频率动态进行了分析。研究发现,在放射性污染密度为220和1526 kBq/m²(针对¹³⁷Cs)的区域,田鼠的染色体畸变频率在整个研究期间显著超过对照水平3至7倍。1986年至1991 - 1992年期间,居住在不同放射性污染密度(8 - 1526 kBq/m²)区域的所有田鼠种群中,结构染色体损伤频率的动态变化呈现出上升趋势。
