The objectives were to: (1) survey the gamma
radiation from fallout-contaminated ocean areas by means
of aerial detectors and (2) from the aerial detectors
make air-absorption measurements so that the data might
be related to the dose rates at 3 ft above the sea.
Radiation detectors were mounted in P2V-5 aircraft that
surveyed the ocean areas of expected fallout after

Soil samples were exposed to neutron radiation
from Burst Cherokee to help establish the importance of
neutron-induced residual gamma radiation from a
large-yield thermonuclear air burst. After exposure and
recovery, the samples had no detectable activity because
the slant range to the nearest sample was nearly 3.5
Miles, due to an error in bomb drop. After this failure,
an experiment was designed in the field for Burst Yuma
in order that induced-activity data could be obtained
for a soil other than Nevada Test Site (NTS) soil.
Samples of sodium, manganese, and coral sand from Site
Sally were exposed above and below the surface at a
slant range of 120 yards. At this same station, gamma
dose rates were measured and neutron detectors were
exposed by Project 2.51. The full-field gamma radiation
