[S]almon have always been radioactive because they contain radioactive potassium just like we do. Have they become more radioactive as the result of the release of 26 billion Becquerel (Bq) into the Pacific Ocean as reported by Tepco? Unlikely when you consider that this is less than one Curie (Ci) of radioactivity and the oceans contain over 400 billion Ci of radioactivity, 380 from Potassium, 87 from rubidium and 1 from Uranium 238.
