Derivation of dose estimates from subsistence food such as fish require that the concentrations of radionuclide are precisely known. The safety of subsistence food and the ecosystem in areas adjoining Amchitka requires that the radionuclide concentration of anthropogenic radionuclides, potentially released from the three nuclear tests between 1965 and 1971 at Amchitka Island in the central Aleutian Archipelago, in subsistence food. The total yield of these detonations (6.08 million tons) is estimated to be about 15% of the total yield of all US underground nuclear explosions {Long shot: 80 kton at 690 m below the island’s surface; Milrow: 1 million ton, 1969 at 1200 m below surface; and Cannikin: 5 million-ton, 1971 at 1763 m below surface (the world’s largest underground test). The Department of Energy has conducted monitoring of this site for a number of years and has found little evidence of radionuclide leakage (Sibley and Tornberg, 1982; Burger et al., 2006). We collected a suite of fish samples from areas adjoining Amchitka and tested it for natural and anthropogenic radionuclides. In this report, we report the concentration of gamma-emitting radionuclides (40K, 137Cs, 226Ra, and 226Ra) from a suite of fish samples that we obtained from our collaborators.

This research was completed money allocated during Round 5 of the Citizens’ Monitoring and Technical Assessment Fund (MTA Fund). Clark University was named conservator of these works.
