An investigation of the radioactive contamination
of the water and marine organisms in and near the
Eniwetok Test Site was conducted during May 1958,
shortly before and immediately following an underwater
nuclear detonation. At the end of three and one-half
days the boundaries of the radioactive water mass
extended beyond the survey area, 50 miles to the west of
Eniwetok Atoll, and to a depth of at least 300 meters.
The plankton contained high levels of {sup 239}Np, {sup
99}Mo-{sup 99m}Tc, {sup 132}Te-{sup 132}I, and {sup
237}U. Also present in lower amounts were
141}Ce-{sup 141}Pr,
140}Ba-{sup 140}La,
144}Ce-{sup 144}Pr.
{sup
{sup 103}Ru-({sup 103}Rh, {sup
{sup 95}Zr-{sup 95}Nb, and {sup
{sup 106}Ru-{sup 106}Rh and {sup
105}Ru-{sup 105}Rh were detected once in each of two
samples. Whole fish samples contained essentially the
same radioisotopes as the plankton. Shrimp and squid
contained high levels of {sup 239}Np and {sup
BOl.

(United
The radiofrequency reflection and absorption
effects of shots Teak and Orange detonated over Johnston
Island in August 1958 were examined. Five radars in the
10- and 1000-Mc range were used in the search for
