Modifications of agricultural and zoo-technical practices to reduce food chain contamination

Many methods for decreasing radioactive transfers all along the food chains may be used for post-accidental situations. In some contaminated CIS countries (Ukraine, Belarus), real size applications have quantified these methods for vegetables transfers (liming, fertilizers, zeolite...), for animals transfers (iodine, clay, cyanoferrates...), and for soil rehabilitation (striping, deep ploughing...).
