LIVESTOCK FARMING TECHNOLOGIES IN CASE OF LARGE-SCALE RADIOACTIVE CONTAMINATION (TO 35TH-ANNIVERSARY OF THE CHERNOBYL NPP ACCIDENT)

Abstract

On the example of the Chernobyl NPP accident, the problems of animal husbandry in case of radioactive contamination of hayfields and pastures are shown. The factors determining the accumulation of radionuclides in milk and meat are presented. It is noted that the excess of radiological standards for the content of 137Cs in livestock products in the southwestern districts of the Bryansk region is long-term and requires continuation of rehabilitation work. A classification of countermeasures and technologies in animal husbandry carried out after the Chernobyl accident is given. It was shown that the most effective was the use of Cs-binding sorbents - hexacyanoferrates for lactating cows and fattening cattle. Farms in the southwestern districts of the Bryansk region have been identified, where until now there is a risk of exceeding the standards for the content of radionuclides in livestock products. For these farms, a scheme for the use of hexacyanoferrates was proposed depending on the levels of 137Cs contamination of grassland.
