Abstract | The Fukushima Daiichi power station released several radionuclides into the Pacific following the March 2011 earthquake and tsunami. A total of 26 Pacific albacore (Thunnus alalunga) caught off the Pacific Northwest U.S. coast between 2008 and 2012 were analyzed for ¹³⁷Cs and Fukushima-attributed ¹³⁴Cs. Both 2011 (2 of 2) and several 2012 (10 of 17) edible tissue samples exhibited increased activity concentrations of ¹³⁷Cs (234−824 mBq/kg of wet weight) and ¹³⁴Cs (18.2−356 mBq/kg of wet weight). The remaining 2012 samples and all pre-Fukushima (2008−2009) samples possessed lower ¹³⁷Cs activity concentrations (103−272 mBq/kg of wet weight) with no detectable ¹³⁴Cs activity. Age, as indicated by fork length, was a strong predictor for both the presence and concentration of ¹³⁴Cs (p < 0.001). Notably, many migration-aged fish did not exhibit any ¹³⁴Cs, suggesting that they had not recently migrated near Japan. None of the tested samples would represent a significant change in annual radiation dose if consumed by humans. |
