Country of Origin: United States Country of Publication: United States Abstract: The increased incidence of thyroid nodularity and carcinoma appearing as a late effect after exposure of the human thyroid to ionizing radiation is well-recognized. Despite the high prevalence of thyroid nodularity in Marshallese inadvertently exposed to fallout in 1954, only two subjects, both about one year of age at exposure, have been found to have primary hypothyroidism. The recent availability of sophisticated immunoassay techniques for thyroxine (T/sub 4/) and thyrotropin (TSH) has allowed more thorough thyroid evaluation of the exposed population who do not have known thyroid abnormalities (43 Rongelap people). Four of 43 Rongelapese had abnormally high basal TSH and TRH-induced. TSH release on two such tests as opposed to only 2 of 214 controls. Plasma T/sub 4/ concentrations were low, or low-normal in these individuals. These results indicate the presence of early thyroid dysfunction. Several other subjects have shown at least one abnormal finding but have not had the required number of tests to meet the established criteria. In /sup 3///sub 4/ of these subjects the estimated thyroid exposure dose was less than 400 rads. Hypothyroidism has been previously noted after therapeutic doses of /sup 131/I for hyperthyroidism, levels but not in individuals exposed to the relatively low of thyroidal radiation (less than 400 individuals. ; rads) estimated for these Major Descriptors: *FALLOUT -- BIOLOGICAL RADIATION EFFECTS; *HYPOTHYROIDISM ~- RADIOINDUCTION; *MAN -- BIOLOGICAL RADIATION EFFECTS 7; *MAN -- LOW DOSE IRRADIATION; *MARSHALL ISLANDS -- FALLOUT; *THYROID ~~ BIOLOGICAL RADIATION EFFECTS Descriptors: DELAYED RADIATION EFFECTS; HUMAN POPULATIONS; INTERNAL IRRADIATION; PHYSIOLOGY; THYROID HORMONES Broader Terms: ANIMALS; BIOLOGICAL EFFECTS; BIOLOGICAL RADIATION EFFECTS; BODY; DISEASES; ENDOCRINE DISEASES; ENDOCRINE GLANDS; GLANDS; HORMONES; IRRADIATION; ISLANDS; MAMMALS; ORGANS; PEPTIDE HORMONES; POPULATIONS; PRIMATES; RADIATION EFFECTS; VERTEBRATES Subject Categories: 560171* -- Radiation Effects -- Nuclide Kinetics & Toxicology -- Man -- (-1987) INIS Subject Categories: C21* -- Tissue Distribution, Metabolisnt, Toxicology & Removal of Radionuclides 103) 00381672 ERA-03-038247; EDB-78-076075 Author(s): Coles, c (Item 654 from file: Title: Effects of temperature on photosynthesis and respiration in hermatypic corals S.L.; Jokiel, P.L.
