Publication Date: 1963 33 p. Primary Report No.: BNL-7145; CONF-150-1 Secondary Report No.: CONF-150-1 Note: From Congress of Science on Humans, York, June 1963 } 2nd Annual Conference, Journal Announcement: NSA17 Document Type: Report Language: English Contract No.: AT-30-2-GEN-16 ‘ New The acute and residual effects of a localized fallout exposure on the people of Rongelap island are summarized for the 8-yr period subsequent to their accidental exposure on March 1, 1954. The accident occurred following the detonation of a high-yield nuclear device at the Pacific Proving Grounds. Twenty-three Japanese fishermen aboard the Lucky Dragon were also exposed. The 64 inhabitants of the island, located 105 nautical miles from the detonation, received an estimated dose of 175 r of whole-body gamma radiation, contamination of the skin sufficient to result in BETA burns, and slight internal absorption of radioactive materials through inhalation and ingestion. The fallout resembled a light snowfall. The exposed people were evacuated about 2 days after the accident and received extensive examinations for the following 3 mo. Annual medical surveys have revealed only minimal residual effects in the exposed population. (C.H.)

Gorbman, A.; James, M.S. "Radioecology" Columbia Univ., New York Publication Date: 1963 385-99 p. Publ: Reinhold Publishing Corporation; Washington, Institute of Biological Sciences D.C., The American Journal Announcement: NSA17 Document Type: Book Analytic Language: English Three series of coral reef fishes, totaling 175 specimens and representing 79 species and 25 families, were collected at Eniwetok Atoll in the Marshall Islands at one-month and eight-month intervals after a nuclear explosion. Two of the series included fishes from both a near and a distant site within the atoll, relative to the explosions. Serial sections of the thyroid regions revealed varying amounts of necrotic alteration in many specimens, suggesting a thyrotoxic level of iodins-131 in the environment. Using a rough scoring system, it was possible to estimate the relative degree and extent of thyroid damage and to express it numerically for comparison with other individuals. Histopathologic changes observed are described. (C.H.)
