Radiological and economic efficiency of the cesium-137 sorbent

Abstract

On the territory of radioactive contamination, in the system of measures aimed at reducing the uptake of radionuclides by livestock products, a large place is occupied by the methods of introducing cesium-binding sorbents into the diets. However, the disadvantage of their use is the lack of the local production in Belarus.The article discusses the radiological and economic efficiency of the caesium-137 sorbent of the Belarusian origin. It has been established that the Belarusian-made enterosorbent in the diet of rabbits at a dose of 2 g/head, 4 g/head and in the diet of bulls at a dose 40 g/head is 1,4, 2,6 and 1,15 times respectively more effective than pure ferrocine. Starting from the 5th to the 20th day of using the carbon sorbent, there is a decrease in the content of cesium-137 in the milk of cows from 1,7 to 4,5 times.The cost per 1 thousand Bq of the difference in the accumulation of cesium-137 in rabbit meat in case of the Belarusian sorbent at a dose of 2 g/head by 7,6 times lower in comparison with ferrocine, at a dose of 4 g/head by 4,0 times, in beef by 5,5 times, in milk by 5,2 times lower.
