Radiocesium Concentrations in the Body Homogenates and
Several Body Compartments of Naturally Contaminated White-Tailed Deer
Lehr Brisbin, Jr. and Michael H. Smith
Radiocesium concentrations were determined for
various tissues, organs, and other body compartments of 17 white-tailed deer
collected from contaminated habitats on the AEC Savannah River Plant.
Higher levels of radiocesium concentrations were found in skeletal
muscle, feces, kidney, and adrenal tissue, which averaged between 50 to 70 pCi
radiocesium/g (dry weight). Liver
and bone showed the lowest average values.
With the exception of feces and rumen contents, nearly all tissues and
organ compartments showed significant positive linear correlations between their
respective radiocesium levels. Analyses
of whole-body homogenates indicated that the deer examined averaged 9.91 pCi
radiocesium/g (whole-body wet weight). These
values were best predicted from the radiocesium contents of skeletal muscle,
using the relationship: pCi
radiocesium/g dry whole-body weight = 3.33 + 0.60 (pCi/g dry skeletal muscle).
Calculations of a weighted “predictive index” indicated that
concentrations in skeletal muscle best predicted the overall pattern and levels
of radiocesium distribution within all compartments of the deer body.
Radiocesium concentrations in the brain, heart, and liver, respectively,
followed muscle in order of predictive ability.
