Country of Origin: United States Country of Publication: United States Abstract: Results are summarzied from a medical survey carried out in March 1958 on inhabitants of the Rongelap Islands exposed to accidental fall-out radiation during Operation Castle n the spring of 1954. The habitation of these people on Rongelap Island affords the opportunity for a most valuable ecological radiation study on human beings. The various radionuclides present on the island can be traced from the soil through the food and into the human being, where the tissue and organ distributions, biological half-times, and excretion rates can be studied. No apparent acute or subacute effects were found at this time related to the gamma dose of 175 r received, with the possible exception of hemopoietic findings indicating a persisting lag in 9003983 complete recovery of platelet levels of the peripheral blood. In the males these mean levels were 11 to 16% and in the females 9% below the corresponding mean levels of the comparison population. History and physical examinations revealed no clinical evidence of any iliness or findings during the past year or at the time of the survey which could be related to whole-body exposure. Estimates of body burdens ‘of radionuclides were determined by gamma spectroscopy and by radiochemical analyses of urine samples. These measurements showed an increase in the body burden of cesium-137, strontium-90, and zinc-65. Surveys were also made on the incidence of intestinal parasites, and on blood groups and anthropological background of the Marshallese. ; Major Descriptors: *FALLOUT -- RADIATION HAZARDS; *HUMAN POPULATIONS -MEDICAL SURVEILLANCE; *HUMAN POPULATIONS -- RADIATION HAZARDS Descriptors: ANTHROPOLOGY; BIOLOGICAL HALF-LIFE; BIOLOGICAL RADIATION EFFECTS; BLOOD; BLOOD GROUPS; BLOOD PLATELETS; BODY BURDEN; CASTLE PROJECT; CESIUM 137; ENVIRONMENTAL EXPOSURE PATHWAY; EXCRETION; FOOD; FOOD CHAINS; GAMMA RADIATION; GAMMA SPECTRA; HEMATOPOIETIC SYSTEM; MARSHALL ISLANDS; NUCLEAR EXPLOSIONS; PARASITES; RADIATION DOSES; RADIOCHEMICAL ANALYSIS; SOILS; STRONTIUM 90; TISSUE DISTRIBUTION; URINE ; WHOLE-BODY IRRADIATION; ZINC 65 Broader Terms: ALKALI METAL ISOTOPES; ALKALINE EARTH ISOTOPES; BETA DECAY RADIOISOTOPES; BETA-MINUS DECAY RADIOISOTOPES; BETA-PLUS DECAY RADIOISOTOPES; BIOLOGICAL EFFECTS; BIOLOGICAL MATERIALS; BIOLOGICAL WASTES; BLOOD; BLOOD CELLS; BODY; BODY FLUIDS; CESIUM ISOTOPES;
