[The individual characteristics of 90Sr accumulation in the body of 2 species of the common vole inhabiting the territory of the eastern Urals radioactive trace].

Individual peculiarities of 90Sr skeleton deposition in voles M. gregalis and M. arvalis inhabiting at the territory of East Ural Radioactive Trace were investigated. More high accumulation of radionuclide in the organism of M. gregalis was registered. Considerable variations (3-6 times more, than in linear mice ones) of individual indices of radionuclide accumulation exceeding interspecies level are found. Possible reasons of both interspecies differences and an individual deposition' variability were discussed.
