Abstract: In the territory of All-Russian research institute of biological plant protection (Russian academy of agricultural sciences), in the field in orchard, difference in the vertical migration of radionuclides (90Sr) was studied in the soil layer of ordinary leached chernozem, depending on the depth of its original location.

Abstract: The article provides the results of a comparative analysis of radionuclides (226Ra, 232Th, 40K, 137Cs). It reveals the consistent patterns of their activity distribution (the content) in the profile of chernozems exploiting in agriculture and their analogues under forest (field-protective forest) and old idle land. The soil samples were selected in Volgograd, Rostov and Orenburg regions and Republic of Bashkortostan.

Abstract: The effect of Co and Zn on the accumulation of 60Co and 65Zn by plants was studied in experiments with growing barley on a soddy-podzolic soil and a chernozem containing the radionuclide and increasing concentrations (from the background level to a high degree of contamination) of the corresponding metal. The root uptake of 60Co was directly related to the soil contamination with Co and its accumulation in the plants, while an inverse relationship was observed between the activity of 65Zn in the plants and the content of Zn in the soil. It was concluded that the transfer of the radionuclide into the plants under mixed radioactive and chemical contamination depended, on the one hand, on the mobile reserve of the stable nuclide in the soil and the solid phase potential to release its ions into the soil solution and, on the other hand, on the requirement of the plants for this element and the uptake rate of its ions by the roots from the solution.
