The distribution and the biological half-lives of 137Cs in poultry after continuous intake of foodstuffs contaminated by the Chernobyl fallout were studied in order to determine transfer coefficients to yolk, albumen, and shell of eggs as well as transfer coefficients to chicken meat. Mean values for laying hens were found to be 0.2 d kg-1 (whole consumable egg), 1.2 d kg-1 (leg meat), and 1.6 d kg-1 (breast meat) when radiocesium was fed in contaminated grass pellets, and about twice as large [i.e., 0.4 d kg-1 (whole consumable egg), 2.8 d kg-1 (leg meat), and 3.0 d kg-1 (breast meat)] when radiocesium was fed in contaminated wheat. Reducing effects of the feed additive ammonium-ferric-cyano-ferrate in concentrations of 0.66 g kg-1 of feed mixture on the contamination of hen products were quantified to be a factor of 3 to 4 (whole consumable egg and meat after grass pellet feeding) and 8 to 14 (whole consumable egg and meat after wheat feeding). A drastically higher reduction with an ammonium-ferric-cyano-ferrate dose twice as large (1.33 g kg-1) was achieved. For broiler chickens, activity concentration ratios of meat to feed were derived for various fattening periods, with mean values of about 0.3 (leg), 0.4 (breast), and 0.2 (liver). The addition of ammonium-ferric-cyano-ferrate reduced the activity concentrations in meat by factors of more than 6.
为了确定铯 - 137向蛋黄、蛋清、蛋壳以及鸡肉中的转移系数，研究了家禽持续摄入受切尔诺贝利放射性沉降物污染的食物后铯 - 137的分布情况及其生物半衰期。结果发现，当以受污染的草颗粒饲喂含放射性铯的产蛋母鸡时，向整个可食用鸡蛋、腿肉和胸肉的转移系数平均值分别为0.2 d kg⁻¹、1.2 d kg⁻¹和1.6 d kg⁻¹；而当以受污染的小麦饲喂时，上述转移系数约为之前的两倍[即分别为0.4 d kg⁻¹（整个可食用鸡蛋）、2.8 d kg⁻¹（腿肉）和3.0 d kg⁻¹（胸肉）]。饲料添加剂亚铁氰化铁铵浓度为0.66 g kg⁻¹饲料混合物时，对母鸡产品污染的降低效果经量化后发现，对于草颗粒饲喂后的整个可食用鸡蛋和肉，该效果为3至4倍；对于小麦饲喂后的整个可食用鸡蛋和肉，该效果为8至14倍。当亚铁氰化铁铵剂量加倍（1.33 g kg⁻¹）时，实现了更高幅度的降低。对于肉鸡，得出了不同育肥期肉与饲料的活度浓度比，腿肉、胸肉和肝脏的平均值分别约为0.3、0.4和0.2。添加亚铁氰化铁铵使肉中的活度浓度降低了6倍以上。
