[Biological effects in natural populations of small rodents in radiation-polluted territories. Dynamics of chromosome aberration frequency in a number of generations of European bank vole (Clethrionomys glareolus, Schreber)].
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).
