Health risks of the nuclear industry go very much under the radar of governments, policy-makers, and the public. Each stage of nuclear power generation, from uranium mining, refining and day-to-day activity of nuclear reactors, releases small amounts of radioactivity into the environment on an ongoing basis. As physicians, we see nuclear power as a serious threat to public health.

How will history's largest accidental deposit of radiation in the ocean affect our Pacific fish? And will any of these contaminated plants or fish work their way up the food chain or directly onto our North American plates?
