ASSESSMENT THE HEMATOPOIETIC SYSTEM IN SMALL MAMMALS FROM AREAS WITH LOW RADIATION POLLUTION
We studied the number and cellular composition in blood counts and blood-forming organs of small mammals (<i>Mus musculus, Apodemus sylvaticus, Clethrionomys rutilus</i>) from areas exposed to irradiated action (East Ural Radioactive Trace, Sverdlovsk region, Totsky radioactive trail, Orenburg region). Changes of the composition and structure of blood cells, of the cellular composition and the concentration of cells in hematopoietic tissue depended on the species and habitats animal. The identifi ed radionuclides in animal confi rms the impact on the body of mice and voles radiation factor environment.
