Abstrakt: The influence of Bifezh (a hexacyanoferrate compound as veterinary feed additive) on the transfer of 137Cs to meat was investigated in broiler chickens after application of an artificially contaminated feed mixture. The reduction factors reached 2.23 and 8.46 for single and multiple 137Cs administration, respectively. The elimination rate of 137Cs in the decontamination period was only slightly increased by Bifezh. The reduction effect of Bifezh was considerably and positively limited by various amounts of the additive during both radiocaesium accumulation and decontamination. No significant differences in the reduction effect between breast and thigh meat were observed. In conclusion, the hexacyanoferrate-cellulose binder Bifezh can be recommended as an alternative chemical measure for reducing 137Cs contamination of broiler chicken meat, although administration rates may need to be enhanced over those currently recommended.
