The migratory tuna transported radioactive particles across the ocean in just 5 months, according to the study, published online today (May 28) in the Proceedings of the National Academy of Sciences.
But the findings are not necessarily bad: the levels of radioactivity in the fish are not high enough to be a health concern, the authors emphasized, and the radiation ...
