THE EVALUATION OF EFFICIENCY OF THE FERROCYANIDES FOR THE REDUCTION OF *991*993*997Cs CONTENT IN THE CATTLE PRODUCTS

Abstract

The dependence of the efficiency of the ferrocyanide preparations (for the reduction of the radiocesium accumulation in the animal's organism) on the different conditions of its use had been studied. The results have been obtained in the course of 5 experiments on the cattle and sheeps, using the foods, to be contaminated as a result of the Chernobul AES emergency (10 to 180 kBk/kg). It has been established, that under the conditions of the cattle-keeping farm, preparations Ferrocine-2, Bifezh and CINOM show practically the same efficiency. For the first time it has been shown that, the older the animals the lower is the efficiency of the ferrocyanides; the intensity of leading the radiocesium out at application of ferrocyanides is proportional to the initial content of radionuclides in the organism; the longer time the ferrocyanide is being used, the higher its efficiency; on the method of design of the efficiency its value depends. The recommendations on the most optimum use of the preparations have been given. The results of the work have been used in the performance of the complex program "Ferrocyanide". They are necessary in the agricultural practice and in the scientific investigations, and in the development of the recommendations on application of ferrocyanidesAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
