Transfer coefficients to eggs and meat were determined after acute oral doses of 95mTc, 99Mo, 123mTe, 133Ba, 131I, 95Zr and 95Nb to laying hens. The mean values (in units of d kg-1) to eggs and hen meat were, respectively, 3.0 and 0.03 for Tc, 0.87 and 0.18 for Mo, 5.1 and 0.60 for Te, 0.87 and 9.2 X 10(-3) for Ba, 3.2 and 0.01 for I, 2 X 10(-4) and 6 X 10(-5) for Zr, and 1 X 10(-3) and 3 X 10(-4) for Nb. For the same radionuclides administered in the same chemical form, transfer coefficients for eggs are about one to two orders of magnitude higher than for cow's milk, while the transfer coefficients for hen meat are several orders of magnitude higher than for beef.
在给产蛋母鸡经口急性给予95mTc、99Mo、123mTe、133Ba、131I、95Zr和95Nb后，测定了它们在鸡蛋和肉中的转移系数。对于鸡蛋和母鸡肉，Tc的转移系数平均值（单位：d kg-1）分别为3.0和0.03，Mo为0.87和0.18，Te为5.1和0.60，Ba为0.87和9.2×10(-3)，I为3.2和0.01，Zr为2×10(-4)和6×10(-5)，Nb为1×10(-3)和3×10(-4)。对于以相同化学形式给予的相同放射性核素，鸡蛋的转移系数比牛奶高约一到两个数量级，而母鸡肉的转移系数比牛肉高几个数量级。
