Summary 1. Radiocesium elimination in Trachemys scripta was found to follow a typical exponential decay curve, with no difference in elimination rate constants between turtles kept indoors in a controlled environment chamber, and others kept outdoors in an experimental pond. 2. Radiocesium elimination rate constants ranged from 0.0028-0.0138 day-1 (x= 0.0072 ± 0.0044 (S.E.) day-1) 3. There was no significant relationship between radiocesium elimination rate constant and sex of the turtle. 4. There was a positive exponential relationship between turtle body mass and radiocesium elimination rate constants. 5. There was positive correlation between turtle body mass and the initial body burden of the turtle. 6. Iterative regressions of the elimination data showed that 12-13 weekly determinations of 137Cs total body burdens were necessary to adequately estimate the 137Cs elimination rate constant of Trachemys scripta.
