Determination of the transfer of cesium and iodine from feed into domestic animals.

The 137Cs transfer coefficients for meat were: 0.01 d/kg beef (cow), 0.038 d/kg beef (heifer), 0.038 d/kg (bull), 0.35 d/kg veal, 0.4 d/kg pork, 0.33 d/kg sheep, 0.28 d/kg fallow deer and 1.3 d/kg chicken. The transfer coefficients for cow's milk were 0.007 d/1 (131I) and 0.003 d/1 (137Cs), and for sheep's milk 0.06 d/1 (137Cs). In egg-white and yolk transfer coefficients for 137Cs of 0.2 and 0.1 d/kg, respectively, were determined. Biological half-lives and the influence of feed additives on the activity concentrations in meat and animal products are described
