Transfer coefficients of selected radionuclides to animal products. II. Hen eggs and meat.

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.
