Abstract

Radioactive contamination refers to the physical contamination, since the introduction into the environment of a source of energy, manifested in a deviation from the norm of its physical properties. Radioactive substances deposited on the soil surface can move in the horizontal and vertical direction under the action of various processes. This leads to the accumulation of hazardous substances in the soil, waterbodies, plants, which enter the human body. Therefore, the main objective of the work is to determine the radiation ambiance on the content of 90Sr and 137Cs in the Altai Republic. More than 100 soil sections and about 50 plant species were analyzed for the study. The authors represented the data on the content of artificial radionuclides (137Cs, 90Sr) in the soil-plant system. The content of nuclides in different types of soils developed under the conditions of vertical zonation has been determined. The accumulation of radioactive elements by plants depends on their content in soils, the type of soil, and properties of soils, and the species of plants. It has been established that the content of 137Cs and 90Sr in the soil-plant system of the unexplored territory is fixed at the level and below the limit permissible values.
