Evalwations of the cadieective centaminats op ef btological organiews® in the vicinity ef the Eniwetok Test Site
have been made by the Labovatory of Radiation Biology since
Operation Crossroads
.:n 1945.
In order to determine the
gvographical limity of the contamination, the area of the
Surveys was extended ,in 19$4,to include several telands away
from the test vitc.
The “off{-sits” collecting areas,

Islands and were selected because of their diree-
tior and distance
from Eniwetok as wt)] ae their accessibility.
Surveys made at tl :ge is.anids
showed that in 1354 ans
in 1954,
1955,
1956, and 1958
1.954 the rediouctivity decreased with
i
distance and d:i:ection from the teet site and that at the
islands within a 1Weoale radius the radieactivity was approximately ten iw more ‘imes that of the other islands.
