"'Fears regarding environmental radioactivity, often a legacy of Cold War activities and distrust of governmental and scientific authorities, have resulted in perception of risks by the public that are not commensurate with actual risks,' wrote marine biogeochemist Nicholas Fisher of Stony Brook University in New York and his co-authors in Monday's online edition of the journal Proceedings of the National Academy of Sciences."

A hypothetical fisherman who consumed about five times as much fish as the average American would get a dose of around 2.8 millisieverts over a year, of which only 4.7 microsieverts would come from cesium, and Fukushima. That's about the same amount of radiation a person receives when getting a dental X-ray, the team wrote. The increased probability of developing a fatal cancer for the hypothetical fisherman was 0.00002%, the equivalent of two additional cancers per 10 million people eating the relatively larger amount of fish.

'This study shows that the committed effective dose received by humans based on a year's average consumption of contaminated Pacific bluefin tuna from the Fukushima accident is comparable to, or less than, the dose we routinely obtain from naturally occuring radionuclides in many food items, medical treatments, air travel and other background sources,' Fisher and his co-authors wrote."
