Fukushima fish still contaminated from nuclear accident

Levels of radioactive contamination in fish caught off the east coast of Japan remain raised, official data shows.

It is a sign that the Dai-ichi power plant continues to be a source of pollution more than a year after the nuclear accident. About 40 percent of fish caught close to Fukushima itself are regarded as unfit for humans under Japanese regulations. The respected U.S. marine chemist Ken Buesseler hasreviewed the data in this week’s Science journal.
