After major nuclear accidents the most effective action to reduce activity levels in animal products is to provide uncontaminated feed or feed diluted with uncontaminated material. However, uncontaminated feed may not always be available in such situations. Therefore other effective procedures are needed to reduce activity levels which must be easy to apply, low in cost and have no side effects on animals and their products. Chemical substances administered as feed additive to housed or grazing animals act by influencing gut absorption or increasing the rate of excretion from blood and organs. The main chemical methods used are: (1) dilution of radionuclides by stable isotopes or analogous inactive elements; and (2) natural or artificial binding agents. In this paper a summary and critical review of the different chemical methods described in the literature is given.
在重大核事故之后，降低动物产品中放射性活度水平的最有效措施是提供未受污染的饲料，或用未受污染的物质稀释饲料。然而，在这种情况下，未受污染的饲料并非总能获得。因此，需要其他有效的方法来降低放射性活度水平，这些方法必须易于实施、成本低廉，并且对动物及其产品无副作用。作为饲料添加剂给予圈养或放牧动物的化学物质，通过影响肠道吸收或提高血液和器官的排泄速率来发挥作用。主要使用的化学方法有：（1）用稳定同位素或类似的非活性元素稀释放射性核素；（2）天然或人工结合剂。本文对文献中描述的不同化学方法进行了总结和批判性综述。
