Radiocesium in Birds of the Savannah River Plant
O. Straney, Barbara Beaman, I. L. Brisbin, Jr. and M. H. Smith
Radiocesium body burdens were determined for 255
birds which were collected in the summers of 1971 and 1972 at six locations on
the AEC Savannah River Plant near Aiken, South Carolina.
The results suggest that juvenile and adult birds have different patterns
of radiocesium uptake which would render them not directly comparable.
Juvenile birds showed no significant differences in radiocesium body
burden due to locations or diets. Significant
levels of radiocesium were found in adult avian communities inhabiting areas
near a reactor waste effluent stream and adjacent to a radioactive waste burial
ground. Levels of radiocesium in
communities from areas more peripheral to the effluent stream and a reactor
cooling reservoir, as well as from two control areas were not statistical
distinguishable from background. Differences
were also apparent due to the diets of birds at each location.
Despite the mobility of birds, major environmental discontinuities seem
to act as effective barriers to the lateral movement of radionuclides in such
