“…The disassembly basin efnuents contained a number of fission products, mainly 137Cs, which leaked from failed experimental fuel cells (Ma70). Two hundred and sixty-seven curies of radiocesium had been discharged into Steel Creek by 1973 (Ma74).…”

The accumulation of radiocesium was studied in hand-reared wood ducks which were released into a South Carolina swamp habitat which had been contaminated with production reactor effluents. The uptake of radiocesium by the ducks was described as:In pCi radiocesium/g live body weight = 0.36 + 0.18 (days). There was no effect of sex on uptake rate. The average estimated time required to attain practical equilibrium (0.90 Q,) was 17.3 days, with a range from 10.2 to 26.8 days. Ducks which were recaptured after attaining equilibrium concentrations in the field (averaging 16.6 pCi radiocesium/g live body weight) showed single-component elimination-rate curves when confined in a seminatural pen for elimination studies. Radiocesium elimination under penned conditions was described as: In YO initial body burden = 4.60-0.13 (days). Elimination-rate and body weight showed a negative linear correlation for the penned birds although there was no effect of sex on loss-rate. Radiocesium biological half-times for the penned ducks averaged 5.6 days with a range from 3.2 to 9.3 days. Calculations based on biological half-times determined from studies with the penned birds, were successful in accurately predicting both the levels and rates of radiocesium accumulation by free-living birds in the field.

“…It has been estimated that ~500 Ci (1.9 X 1013 Bq) of 137Cs has been released into surface waters on the SRP reservation between 1961 and 1973, and that ~18% of this total release or 90 Ci (0.3 X 1013Bq) has drained into the Savannah River (26).…”
