Chemical methods to reduce the radioactive contamination of animals and their products in agricultural ecosystems

摘要: After major nuclear accidents the most effective action to reduce activity levels in animal products is provide uncontaminated feed or diluted with material. However, may not always be available such situations. Therefore other procedures are needed which must easy apply, low cost and have no side effects on animals their products. Chemical substances administered as additive housed grazing act by influencing gut absorption increasing rate of excretion from blood organs. The main chemical methods used are: (1) dilution radionuclides stable isotopes analogous inactive elements; (2) natural artificial binding agents. In this paper a summary critical review different described literature given.
