Very very small amounts of radiation is not bad. Your body is exposed to this every day.

Japans plan is to dilute the "water" so much that it should be at safe levels while it decays. They're also not going to release all of it at once, which might not be clear to some readers.

I believe their plan is widely recognized to be safe, but obviously there is a lot of fear around nuclear and radiation.

I believe the worry is that this amount has never Been released before, and that while we might consider it safe, there is a chance it accumulates somewhere to harmful levels.

And obvious consumers of fish are already reacting. Would you buy "safe" fish from Chernobyl if you could just as easily buy the same fish from South Korea?
