Test plantings of food crops may be conducted on each of the
"no crops" islands as designated by the Enewetak people. As
edible parts of these plants become available, concentrations
of significant radionuclides should be measured and compared
with the radiological survey predictions. These studies will
indicate times at which planting of subsistence and commercial
crops can be safely resumed.
0. Lenswater sampling and analysis should be conducted, samples
to be taken over a period of at least 12 calendar months.
Bacterial content, salinity, and radionuclide content should be
measured. Radioactivity information will contribute to an
understanding of processes operating - or whigh can be ymade to
operate - to reduce the ecological half-life of Ose and 137s
below the radioactive half-life on the northern islands, especially
Enjebi (Janet).
.
ll. A comprehensive air sampling program should be conducted
‘over a period of 12 consecutive months under conditions closely
approximating human habitation and expected soil disturbance
to provide information on radioactivity levels in air. This
program could be conducted coincident with and support cleanup.
