Frequency Distributions of Radiocesium Concentrations in Soil and Biota

John E. Pinder III and Michael H. Smith



Frequency distributions of radiocesium (primarily 137Cs) concentrations in 33 samples of soils, plants, and animals from contaminated environments of the U.S. Atomic Energy Commissionís Savannah River Plant were compared to normal, log-normal, exponential, and Weibull distributions.  The log-normal and Weibull distributions showed close agreement to many of the samples, but the normal and exponential distributions showed close agreement to relatively few of the samples.  None of the distributions were appropriate for all the samples.  Radiocesium distributions were highly skewed in plants but tended to be less skewed in animals.
