The density of contamination with Sr-90, Cs-137, U, and Pu-239,Pu-240
was determined in the upper layer of the floodland soils near populate
d areas along the Techa river. The radionuclide content and density of
contamination of the earth area are characterized by large irregulari
ty even over the territory of the same populated area. The difference
was found between the soil contamination on the right and left banks.
The density of soil contamination along the Techa river is compared wi
th that due to the South Ural accident and the global radioactive fall
out.
