“…Additionally, three major Russian nuclear weapons production facilities, Chelyabinsk, Tomsk, and Krasnoyarsk, located at the headwaters of the Ob and Yenisey Rivers, which°ow from the Urals into the Kara Sea, discharged over 10 18 Bq of radioactive materials into these two rivers since the early 1950s [2,3]. The announcement about direct dumping of waste into the Arctic Ocean and the potential for future contamination from materials in the Ob and Yenisey Rivers, raised questions regarding exposure of Alaskan native communities through their traditional food supplies, and potential e®ects on Alaskan¯sheries resources [4,5,6,7].…”

Between 1993 and 1995, marine and terrestrial animal samples were collected from the Beaufort Sea and northwest Alaska. These samples were analyzed at Los Alamos National Laboratory for the presence of the anthropogenic radionuclides, 90 Sr, 137 Cs, 238 Pu, 239+240 Pu, and 241 Am. The measurement data were combined with food consumption rates based on survey results for populations residing in three northwest Alaskan communities and published age-dependent ingestion dose coe±cients to estimate potential radiological impacts from the consumption of traditional animal foods harvested in this region.The results of this study indicate that committed equivalent doses to adults from 90 Sr and 137 Cs, due to consumption of traditional food sources, are consistent with currently accepted estimates of average doses to adults in North America due to atmospheric nuclear weapons testing fallout.
