Preliminary Assessment of Radionuclide Exposure

February 17, 2012

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.
