Is there currently any significant human or ecological risk from radionuclides at Amchitka Island?
. Powers C.W., Burger J., Kosson D., Gochfeld M.; University of Medicine & Dentistry NJ cwpowers@eohsi.rutgers.edu Abstract: The Amchitka Expedition provided data on a complex set of geophysical and biological issues that were necessary to assess whether there are currently any risks to humans and marine biota from radionuclides in the marine environment that could be attributable to the nuclear test shots. We found a wide range of biota (both sedentary and migratory) representing multiple trophic levels in the benthic and intertidal habitats around both Amchitka and Kiska (reference site) that could be at risk if there were seepage of contaminants. There is potential for bioaccumulation and biomagnification up the food chain. The geophysical and radiological data on biota were be used to assess whether the foods are safe with respect to radionuclides, whether the levels of radionuclides are currently below published human health risk levels, whether there is any evidence of radionucli
