At Rongelap and Utirik samples were vathered to attempt to correlate
radiation levels
in soil with adjacent
fruit
trees
(pandanus,
coconut, bread-
fruit) and arrowrooct, messerschmidia, scaveola plants for a possible extrapolation purposes at Bikini and Eniwetak where vegetation samples are Limited.
Other samples collected included 24-hour urine samples, water, coconut crabs
and certain marine specimens.
It will be some time before radiochemical analyses
of these samples is completed and the data analyzed.
Gamma spectrographic analysis (whole-body counts) were carried out on 22
people at Utirik, 46 at Rongelap and 31 people at Bikini, including members of
the families who had returned.
These data are undergoing computer analysis.
Preliminary analysis of these data give the following estimated average body

A gamma survey was carried out on Bikini Island using a scintillation type
Survey meter calibrated for |37cs which respresents about 95% of the gamma radiation on the island.
Preliminary analyses showed roughly the following levels on
the island:
