occurred as a result of the ingestion and inhalation of
fallout material from a nuclear detonation lin the Spring
of 1954. An evaluation of the nature and extent of this
internal radioactive contamination was made by a
comparison of the radioelements excreted by the exposed
human beings with data obtained from radiochémical
analysis of the tissues and excreta of animals
contaminated in the same event. The body burden of the
group of human beings with the greatest internal
contamiation was near but did not exceed the maximum
permissible levels for the individual radionuclides.
Radioiodine and radiostrontium were present in highest
concentrations at early times after exposure and were
potentially the greatest internal hazard. The
contribution of the internal radiation to the acute
radiation syndrome observed appears to be small on the
basis of the estimated body burden of the the principal
radioelements. In view of the short half-life of the

The properties of individual fallout particles
produced by nuclear detonations at zero height over
Shallow sea water are analytically described for the
first time. The particles produced during operation
REDWING were slurry masses composed of water, dissolved
and crystalline sea salts, and seawater-insoluble solids
from the weapon, barge, and ocean floor. Special
techniques were used to measure the chloride, water, and
insoluble-solids content of individual slurry particles,
Autoradiography showed that the activity is primarily
associated with the solids. A table of experimental data
