Bluefin tuna record Fukushima radioactivity

Researchers have found elevated levels of radioactivity in pacific Bluefin tuna caught off the coast of California that can be tied directly to the Fukushima incident.

The levels are within safe limits for human consumption, but demonstrate how such pollution can be carried vast distances by migratory species.

Nicholas Fisher, a professor of marine sciences at Stony Brook University in New York says he was 'stunned' to find the radioactive signal in bluefin tuna.
