Description
Radiosilver 110mAg from Chernobyl fallout was measured by γ-spectroscopy with a HP-Ge detector in first cut hay from 1986 with a 110mAg/137Cs ratio of 0.002 and with increasing ratios in livers of mouse, sheep and cattle varying from 0.04 to 1.7. No detectible radiosilver was found in livers of roe deers and humans. Besides 110mAg and naturally occuring 40K typical radionuclides like 90Sr, 131I, 134Cs and 137Cs and less common 129mTe were observed in mammalian tissues only. In an indoor experiment the hay to liver transfer coefficient for 110mAg was determined as 1.5 d/kg in 3 sheep. This transfer experiment was analyzed by means of a one-compartment model. The speculations about the origin of the Silver in the Chernobyl fallout were discussed on the basis of experimental findings. 39 refs., 4 figs., 2 tabs. (author)
