epilation. These lesions healed and hair regrew normally within several months. Radiochemical urine analyses revealed that measurable amounts of radionuclides, including /sup 131/I, were absorbed internally from ingestion of contaminated food and water and from inhalation. No acute effects due to this internal exposure were seen. Late thyroid effects from radioiodine absorption are described. Follow-up examinations have revealed, except for one fatal case of leukemia and extensive thyroid lesions, only a few findings that might be related to radiation exposure. A group of more than 200 Rongelap people who were relatives of exposed people, but had been away from the island at the time of the accident, moved back with the exposed people to their home island in 1957 and have served as an ideal comparison population for the studies. Results of medical examinations carried out on these populations for the past 22 years are reviewed.; Major Descriptors: *HUMAN POPULATIONS -- BIOLOGICAL RADIATION EFFECTS; xHUMAN POPULATIONS -- DELAYED RADIATION EFFECTS; *HUMAN POPULATIONS -EXTERNAL IRRADIATION; *HUMAN POPULATIONS -- INTERNAL IRRADIATION; Xk IODINE 131 -- BODY BURDEN; *MARSHALL ISLANDS -- FALLOUT DEPOSITS; *MARSHALL ISLANDS -- HUMAN POPULATIONS Descriptors: ACUTE IRRADIATION; DOSE COMMITMENTS; LATENCY PERIOD; RADIOSENSITIVITY; THYROID Broader Terms: ACUTE EXPOSURE; BETA DECAY RADIOISOTOPES; BETA-MINUS DECAY RADIOISOTOPES; BIOLOGICAL EFFECTS; BIOLOGICAL RADIATION EFFECTS; BODY; DAYS LIVING RADIOISOTOPES; ENDOCRINE GLANDS; FALLOUT; GLANDS; INTERMEDIATE MASS NUCLEI; IODINE ISOTOPES; IRRADIATION; ISLANDS; ISOTOPES; NUCLEI; ODD-EVEN NUCLEI; ORGANS; POPULATIONS; RADIATION EFFECTS; RADIOISOTOPES Subject Categories: 560151* -- Radiation Effects on Animals -- Man 560161 -- Radionuclide Effects, Kinetics, & Toxicology -- Man INIS Subject Categories: C15* -- Effects of External Radiation on Man C21 -- Tissue Distribution, Radionuclides 10/5/983 00207329 Title: Metabolism, (Item 683 from file: 103) AIX-08-289864; EDB-77-045053 Radioactivity in rain.

Dept. of KAGTA EDB7702 (non-US Atomindex input). existence of radioactivity in rain was discovered by C.T.R. Wilson in Ou08) Country of Origin: United States Abstract: The study related to the natural radioactivity in rain did not make rapid progress in the first half of the 20th century tholigh the 1900. In the latter half of the century, however, a large amount of fission products by nuclear experiments caused the rapid progress in the research on artificial radioactivity in rain. The amount of fission products in rain water as well as in atmosphere has been decreasing recently, and many scholars treat the research on fall-out lightly. The radioactivity in rain owing to the nuclear experiments by China and France is still considerably strong, and a lot of interesting results have been obtained by the study applying the artificial radioactive elements in rain water as the tracer. radioactivity in rain, /sup 210/Pb, Concerning the natural /sup 210/Bi and /sup 210/Po, the long life decay products of radon, may play extremely important role in the field of meteorology and geochemistry in future, as natural radioactive tracers existing in atmosphere in high concentration. ; Major Descriptors: *RAIN -- RADIOACTIVITY Descriptors: BIKINI; CHINA; CONTAMINATION; EARTH ATMOSPHERE; FALLOUT; FRANCE; METEOROLOGY; NUCLEAR EXPLOSIONS; REVIEWS; SEASONAL VARIATIONS; UNDERGROUND EXPLOSIONS = i>
