exposure is the second most significant pathway. Other pathways evaluated are the marine food chain, drinking water, and inhalation. Cesium-137 produces more than 85% of the predicted dose; /sup 90/Sr is the second most significant radionuclide; /sup 60/Co contributes to the external gamma exposure in varying degrees, but is a small part of the total predicted dose; the transuranic radionuclides contribute a small portion of the total predicted lung and bone doses but do present a long-term source of exposure. Maximum annual dose rates for Bikini Island are about 1 rem/y for the whole body and bone marrow when imported foods are available and about 1.9 rem/y, when imports are unavailable. Maximum annual dose rates for Eneu Island when imports are available are 130 mrem/y for the whole body and 136 mrem/y for bone Marrow. Similar doses when imported foods are unavailable are 245 and 263 mrem/y, respectively. The 30-y integral doses for Bikini Island are about 23 rem for whole body and bone marrow when imported foods are available and more than 40 rem when imports are unavailable. The Eneu Island 30-y integral doses for whole body and bone marrow are about 3 rem when imports are available and 5.5 and 6.1 rem, respectively, when imports are unavailable. Doses from living patterns involving some combination of Bikini and Eneu Islands fall between the doses listed above for each island separately.; Major Descriptors: *BIKINI -- RADIATION DOSES Descriptors: CESIUM 137; COBALT 60; DOSE RATES; ENVIRONMENTAL EXPOSURE PATHWAY; FOOD CHAINS; RADIOECOLOGICAL CONCENTRATION; STRONTIUM 90 Broader Terms: ALKALI METAL ISOTOPES; ALKALINE EARTH ISOTOPES; BETA DECAY RADIOISOTOPES; BETA-MINUS DECAY RADIOISOTOPES; CESIUM ISOTOPES; COBALT ISOTOPES; DOSES; ECOLOGICAL CONCENTRATION; EVEN-EVEN NUCLEI; INTERMEDIATE MASS NUCLEI; INTERNAL CONVERSION RADIOISOTOPES; ISLANDS; ISOMERIC TRANSITION ISOTOPES; ISOTOPES; MARSHALL ISLANDS; MICRONESIA; MINUTES LIVING RADIOISOTOPES; NUCLEI; OCEANIA; ODD-EVEN NUCLEI; ODD-ODD NUCLEI; RADIOISOTOPES; STRONTIUM ISOTOPES; YEARS LIVING RADIOISOTOPES Subject Categories: 510302* -- Environment, Terrestrial -- Radioactive Materials Monitoring & Transport -- Terrestrial Ecosystems & Food Chains -- (-1987) 520302 -- Environment, Aquatic -- Radioactive Materials Monitoring & Transport -- Aquatic Ecosystems & Food Chains -- (-1987) INIS Subject Categories: C22* -- Radionuclide Ecology 10/5/728 00955599 Author(s): (Item 428 from file: 103) ERA-~-07-044610; EDB-82-130453 Bainbridge, K.T.

Country of Origin: United States Country of Publication: United States Abstract: This report is intended as a comprehensive record of the July 16, 1945 atomic bomb test at the Alamogordo Air Base. The events leading up™ to Zero, the moment the bomb was detonated are described in detail. Thée™ radiation observations at Trinity, are summarized and compared with thé airburst test at Bikini. All other experimental observations made at ™ the Trinity test are summarized. Possible future atomic bomb tests that might be scheduled to investigate the behavior of bombs of a design o> urs different from the Model 2 Implosion Bomb used at Trinity, Nagasaki, and Bikini are discussed.; Major Descriptors: *NUCLEAR WEAPONS *TRINITY EVENT -- REVIEWS -- TESTING; *TRINITY EVENT -- PLANNING;
