ABSTRACT
During the period of June 11 to 21, 1956, a survey party,
operating from the USS Walton (DE 361), measured the radiation
in plankton, water, and fish samples collected near Bikini and
Eniwetok Atolls.
Fifty-three stations between 10° 15' to 14° N
and 159° to 166° E were covered during the 3,300-mile cruise.
A continuous record of the radiation in the surface water was
obtained with a probe.
Plankton samples from oblique tows to
a depth of 200 meters and water samples from the surface and
from depths of 25,
50, 75,
ity at each station.
and 100 meters indicated radioactiv-
Highest radiation readings in plankton
and water samples were from stations north of Bikini Atoll.
Radiation decreased around the periphery of the survey area.
