RADIONUCLIDE FALLOUT LEVELS FROM THE FUKUSHIMA DAIICHI NUCLEAR DISASTER IN THE ALEUTIAN ISLANDS AND WESTERN COASTAL REGIONS OF ALASKA

Air parcels from the Fukushima Daiichi nuclear disaster crossed over the Aleutian Islands and other regions of Alaska within days of the accident. U.S. Environmental Protection Agency RadNet stations located in Alaska detected radionuclides in the air samples. However, outside of air sampling no other environmental sampling was done at that time. In the summer of 2011, during the Amchitka Island Underground Nuclear Test Site environmental assessment, the Alaska Department of Environmental Conservation and the University of Fairbanks (UAF) School of Fisheries and Ocean Science collected terrestrial and marine samples. These samples and others are being analyzed for Cesium 134 and 137 and other radionuclides at UAF and Lawrence Livermore National Laboratory (LNL). Results of this work will provide information on the magnitude of the Fukushima fallout release in western Alaska coastal regions, providing input into biological uptake models, and help test predictive models of atmospheric fallout deposition.
