A survey of radionuclides in air, precipitation, streams, sediments, soils, and selected plants was conducted in the Olympic National Park, Northwestern Washington State. Thirty-one radionuclides were observed in concentrations that were 3 to 4 fold higher than those observed in arctic Alaska.The environmental factors involved in the movement of these radionuclides through the food web and the trophic levels of the ecosystem were investigated. Rough calculations of the inputoutput relationships are made and trophic levels are compared.
Concentration of the radio nuclide beryllium-7, produced by cosmic rays, was measured in waters collected from both the Atlantic and Pacific oceans. This short-lived nuclide is well suited as a tracer for interactions at the air-sea interface and for the measurement of rapid mixing processes in the surface layer of the ocean.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
