Half-life and Distribution of Radiocesium in a Contaminated Population of Green
Treefrogs Hyla cinerea
W. Dapson and L. Kaplan
Radiocesium content of adult male green treefrogs Hyla
cinerea from a contaminated habitat is adequately described by a log
normal distribution with mean 2.277 log pCi g-1 dry wt (189.2 pCi g-1)
and variance of 0.031. There was
significant negative correlation of body burden with body length and weight
(p<0.05), but the relationship lacked predictive power (r2=0.10).
Biological half-life of radiocesium in unfed, captive frogs held at 20°-30°C
averaged 30.1 d.
