We evaluated 70sr and 13’cs concentrations in coconut meat
and fluid, and papaya meat from Eneu Island (Bikini Atoll) using the same
soil computational algorithms.
Our analyses showed the lognormal probability density assumption to
be correct for data sets having a majority of concentration above the
MDA.
The arithretic mean is an adequate estimator compared to the mini-
Mum variance estimator, particularly when the coefficient of variance is
less than two--this includes 96 percent of the analyzed deta sets.
