When you open your can, check to see if it glows in the dark.

The levels might not be high enough to harm you if you tucked into a tuna sandwich, but some tuna are still carrying radioactive caesium from the leak at the Fukushima Daiichi plant last March. Researchers hope that similarly low levels of radiation in turtles, sea birds and sharks will allow the migration patterns of little-studied species to be tracked.
Daniel Madigan, a marine biologist at Stanford University in California, was already studying how Pacific bluefin tuna (Thunnus orientalis) migrate across the Pacific Ocean when the Japanese tsunami put a new twist on his experiment.
The leak at the Fukushima Daiichi reactor released caesium isotopes into the Pacific, and fish can pick up the radioactive material from the water they swim in and from the food they eat.
Mysterious migrations
Juvenile tuna can take between one and four months to swim the 9000 kilometres from Japan to California. The researchers measured caesium isotopes in young tuna caught off the coast of San Diego, and found detectable levels of caesium-134 in 15 fish. The isotope could not be detected in fish that were caught before 2011.
Because caesium-134 has a half-life of two years, Madigan expects that researchers will be able to find it in the long-lived fish for some time to come. Tuna migration patterns are well known, he says, but the radiation may be useful in tracking other species such as salmon sharks (Lamna ditropis). If these sharks behave as researchers suspect they do, the migratory males would carry Fukushima radiation, but the stationary females would not.

If you leave a piece of tuna out long enough, it'll start glowing without the need for radiation.  |

Its not just the bluefin tuna that will be Radioactive? in fact i would think all whales sharks and fish etc that migrate are infected with the Radiation around the growing Radioactive zone of Japan. |

Fish found in US waters with contamination
At least 10,000km from Japan's nuclear plant

This is a surprise how?

Because the tuna told them himself where he was from. |

Was it a pino tuner? Might have had some key message to impart. |

Is a "pinot tuner" someone who does karaoke after drinking too much wine?
Bluefin tuna stocks are on the way to becoming endangered due to overfishing. Maybe some radioactivity will help. If it doesn't stop people eating them, maybe at least they'll grow to enormous size, thus providing more meat per fish. |

Its not a surprise,i would think we here in Uk also have Radioactive contamination,from Japans nuclear plants. |

The way tuna accumulates heavy metals in its body, definitely time to give up tinned tuna.
Which is a pity, cause I really like the stuff. |
