National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Dose Estimates from Ingestion of Marine and Terrestrial Animals Harvested in the Beaufort Sea and Northwestern Alaska.

PB2001103962

Publication Date	2000
Page Count	20
Abstract	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 coefficients 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.
