ABSTRACT
In the Republic of Belarus after the Chernobyl nuclear power plant accident, 23 percent of the total agricultural land or 1.8 million ha were radioactively contaminated. Of these, 12.9 percent or 1.18 million ha continue to be used for agricultural production. The main sources of the radioactive contamination are long-lived radionuclides cesium-137 (Cs 137) and strontium-90 (Sr-90), wherein greater part of which has got accumulated in the soil. They come from the soil into the atmosphere, water, plants, and are included in the feed and food chain while increasing the dose of external and internal exposure of humans [1]. In this regard, in the agroindustrial complex of the Republic of Belarus, priority is given to the problem of producing standard agricultural products in the contaminated areas. The solution of this problem is impossible without scientific justification and analysis of all the factors that affect the movement and reduction of radionuclides in agricultural products in the process of production and entering into the human body through the food chain: soil→ plants→ farm animals→ livestock products→people [2].
