wis was not detected in breadfruit,
arrowroot,
or
coconut milk at Rongelap or in the internal parts of Pandanus
fruit from Nan Island,
Bikini Atoll.
Since the above samples
represent the internal parts of plants and did not contain
wi8s ,
although leaf samples from the same area did contain
high levels of the isotope,
it is probable that wi85 is not
taken up in significant amounts by plants but occurs rather
as surface contamination.
