a
from the Island of Kabelle which is more heavily contaminated
than the Island of Rongelap).
However, if crabs were eliminated
from the diet, the intake might average about 107 Sunshine Units.
Further,
elimination or restriction of the consumption of
pandanus would reduce the strontium~-90 intake to well under 100
Sunshine Units.
14, There is some doubt concerning the correct strontium90 activity in the land crabs, since the data are higher than
for previous surveys which is contrary to all other data.
Additional surveys should clarify this point.
In any event
the land crabs tested are from the island of Kabelle (there
Were no collections of land crabs made on Rongelap Island
during the last survey).
The general contamination on Rongelap
is about one-fifth that of Kabelle.
The difference in strontium-
90 content may not be aS great as this, but since these are
land crabs it would be expected those on Rongelap Island to be
lower than on Kabelle Island.
15. Estimated Future Body Bumen of Strontium-90.
precise values have not been established,
Although
there is a discrimina-
tory factor between Sr/Ca ratio in the food supply and that
found in the bones.
Animal experiments and limited human data
suggest values of at least a factor of two or three.
16. If the Rongelapese are returned to their home island,
their diet would be supplemented by imported (relatively uncontaminated) foods, especially rice.
Also, the cisterns would
be cleaned out and refilled with fresh water.

the results from all of the surveys on the Pacific Islands show
