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.

Dunning, G.M. Publication Date: nd 69-77 p. Journal Announcement: NSA17 "Nuclear Safety. Vol. 4, No. 3" Document Type: Book Analytic Language: English 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.

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
