Excerpted from Fish Radio:
The results of testing conducted on Alaska fish in 2014, and previously reported by DEC, showed no detection of Fukushima-related radionuclides Iodine-131 (I-131), Cesium-134 (Cs-134), and Cesium-137 (Cs-137). Because scientists were predicting the concentrations of radionuclides in North Pacific waters could peak in 2015, DEC continued the sampling program this summer. Samples in 2015 were again analyzed for Fukushima-related radionuclides and, as in the previous year, had no detectable levels of Fukushima-related radionuclides. These data, along with modeling and monitoring data from multiple agencies and organizations, continue to show fish from Alaska waters are safe from radionuclides related to the nuclear reactor damage in Japan.
