Radiological survey of plants, animals, and soil in micronesia

Description: In 1974 the Laboratory of Radiation Ecology began a program to determine the radionuclides found in foods, plants, animals, and soils of the Central Pacific. As part of this program the present study was undertaken to determine radionuclides found in the common foods and soils in areas of Micronesia other than those areas receiving local fallout from the test sites at Bikini or Enewetak atolls. Areas sampled in 1975 were Majuro Atoll in the Marshall Islands, Truk and Ponape in the Caroline Islands, Guam in the Marianas Islands, and Koror and Babelthaup in the Palau Islands. All samples were analyzed for gamma-emitting radionuclides while some were also analyzed for /sup 90/Sr of /sup 239/ /sup 240/Pu. Results of the analyses indicate that naturally occurring /sup 40/K is the predominant radionuclide in the biological samples. Cesium-137 in amounts less than 1 pCi/g (dry) was the only fallout radionuclide detected in most of the biological samples. Soil samples usually contained /sup 90/Sr, /sup 137/Cs, /sup 238/U, and /sup 239/Pu, while soil from Truk, Palau, and Ponape also contained isotopes of radium and thorium. Soil from Guam also contained /sup 210/Pb and /sup 235/U in addition to the above radionuclides. Considering only the fallout radionuclides, the values for /sup 90/Sr, /sup 137/Cs, and /sup 239/ /sup 240/Pu in samples from Guam, Palau, Truk, Ponape, and Majuro are less than the values for these radionuclides in similar samples from atolls such as Utirik, Rongerik, and Ailinginae in the northern Marshall Islands, and are much less than values of these radionuclides in samples from Bikini and Rongelap atolls.

Freeze Brand Marking of Steelhead Trout and Chinook Salmon Juveniles for Water Budget Studies, Idaho, 1985 Annual Report.

Description: During the fall of 1984 and spring of 1985, 362,428 chinook salmon (Oncorhynchus tshawtscha) and steelhead trout (Salmo gairdneri) juveniles were freeze branded for Water Budget Center - Downstream Smolt Monitoring Studies. Of these, 106,361 fish received a coded wire tag. Release of the freeze brand groups began March 20, 1985 and were completed by June 4, 1985. After brand loss and mortality, there were 133,025 spring chinook, 25,600 summer chinook, 33,850 fall chinook, 65,125 A-run steelhead, and 62,400 B-run steelhead released with brands.

Determination of Elastic Twist in Horizontal Axis Wind Turbines (HAWTs)

Description: This report presents the results of a project at the Alternative Energy Institute (AEI) which measured and calculated the elastic twist of three representative composite horizontal-axis blades: Carter 300, Gougeon ESI 54, and UTRC 8 kW.
