Preliminary Assessment of Radionuclide Exposure
2011 Northern Pinnipeds Unusual Mortality Event
Scientists have conducted preliminary qualitative screening of a few tissue samples from both healthy and sick pinnipeds (ice seals and walruses) involved in this UME for possible radionuclide exposure. No radiation levels were found in these samples that would directly cause the symptoms seen in the pinnipeds. Test results show radiation levels are within the typical background range for Alaska.
