In the Wake of Fukushima: Radiocesium Inventories of Selected North Pacific Fish
Thirteen commonly consumed types of fish caught in the North Pacific and locally available in Hawaii were analyzed using gamma spectroscopy to measure Fukushima-derived and historic 134 Cs and 137 Cs isotopes. All fish samples had detectable 137 Cs above 95% Confidence Intervals. Three out of the thirteen samples had 134 Cs, an isotope indicative of Fukushima releases, detected above 95% Confidence Intervals. The highest 134 Cs and 137 Cs concentration in the examined species was in ahi tuna carrying 0.10±0.04 Bq/kg and 0.62±0.05 Bq/kg, respectively. Other samples with 134 Cs activities found above their 2-sigma uncertainty were albacore tuna and swordfish… Continue reading “Fukushima radiation found in Hawaii fish — Almost half contain fallout from Japan nuclear disaster”
