Abstract: Cleaning up the radionuclide contamination at Enewetak Atoll has
involved a number of statistical design problems. Theoretical
considerations led to choosing a grid sampling pattern; practical
problems sometimes lead to resampling on a finer grid. Other problems
associated with using grids have been both physical and statistical.
The standard sampling system is an in situ intrinsic gamma detector
which measures americium concentration. The cleanup guidelines include
plutonium concentration, so additional sampling of soil is required to
establish Pu/Am ratios. The soil sampling design included both
guidelines for location of the samples and also a special pattern of
subsamples making up composite samples. The large variance of the soil,
sample results makes comparison between the two types difficult anyway,
but this is compounded by vegetation attenuation of the in situ
readings,
soil disturbance influences,
and differences
in devegetation
methods. The constraints inherent in doing what amounts to a research
and development project, on a limited budget of time and money, in a
field engineering environment are also considered. ;
