of radioactive materials through inhalation and ingestion. Eighteen
Rongelap people on a nearby island received an external
dose of about
69 r, and 157 Marshallese on Utirik Island received an estimated dose of 14
xr whole-body radiation. The fallout was not visible on this island and no
skin effects developed. Findings are summarized of surveys made during the
preceding 7 years. Findings are compared with those on comparison
populations of Marshallese people. Data are presented from physical
examinations, a cancer detection and leukemia survey, growth and
development studies in children, ophthalmological examinations, studies on
residual beta burns,
a dental survey, studies of aging criteria, arid
estimation of body burden of Sr/sup 90/. Findings persisting in the exposed
population include incomplete recovery of certain blood elements to levels
found in the unexposed people, retardation of growth and development in
some of the irradiated children, and pigmented changes at the sites of
radiation burns of the sknn. (C.H.)

A review is given of three fallout incidents in which countermeasures
were taken. These incidents were: (1) the multimegaton shot BRAVO in Bikini
Atoll, after which some islanders were evacuated; (2) the 32-kt HARRY shot
at the Nevada Test Site, after which the inhabitants of St. George, Utah,
were asked to remain indoors for 2 hr; and (3) the increase in I/sup 131/
in milk in Salt Jake City after the SEDAN shot, in which case the milk
industry took steps to reduce the I/sup 131/ content. The reasons for each
countermeasure are outlined. It is shown that the actions undertaken on the
milk in Salt Lake City were in iarge measure unnecessary, as the Federation
Radiation Council figures prompting the actions are very conservative and
were to serve only as guides.

RADIATION INJURIES BY NUCLEAR WEAPONS
Ottawa
437-47 p.
Various types of injury of humans from thermonuclear detonations are
discussed, including those resulting from blast, heat, and radiation. The
characteristics of early fallout are described, and the symptoms,
pathology, and treatment of the acute radiation syndrome occurring in
response to exposure to fallout are outlined and discussed. Skin injuries
from fallout are considered, especially with reference in the Marshall
Islanders and Japanese fishermen exposed in 1954. The internal radiation
hazard, resulting from inhalation or ingestion of fission products,
is
