Frequency Distributions of Radiocesium Concentrations in Soil and Biota
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.
