1.
Surveys were made in
1954 to 195d to

and ten off-site’
islands.
The gross beta radivcact.vity decreased with Gietengs
from the test site: 16 1395¢ and 1998 islands whithan a 130mile radius contained at least ten times ag.gech radiocace
tivity as the other islands.
4.
The levels of radioactivity also were related toe Girec-
tion from the test site.
In 1955 the islands ts the east
contained hijzh levels of radioactivity.
Tarawa.
Im 1956 and 19538
1300 miles southeast of the test site, contained very
low levels whereas Kapingamaringi,
distance to the southwest,
appr@@imately the same
contained significantly higher
arnounts of radioactivity.

2r25-N095 and RutY3. 106.pp,103, 106 were the predominant
radioisotopes present in the majority of the samples.
