Radiation from Japan nuclear plant arrives on Alaska coast

Radiation from the Fukushima power plant has been detected in Canada and Alaska.  The report doesn't say how much radiation has arrived.  It just gives a vague fear that we don't know what the effect on seafood and wildlife will be.

Yes, we don't know that - but if we don't know the quantity of radiation how do we know whether this is a major thing, or a minor thing?

The only statement of the severity is this - "The levels they are projecting in some of the models are in the ballpark of what they saw in the North Pacific in the 1960s," said Douglas Dasher, a researcher at the University of Alaska Fairbanks.

The article does point out that there is no routine monitoring, so therefore it's not known whether radiation levels are increasing or decreasing.

The statement, "North Pacific in the 1960's," refers to the fallout from US Nuclear testing on islands in the Pacific during the 1950's and 1960's.  That testing was deemed necessary to fend off Communism.  But it obviously left a fair bit of radioactive contamination in the Ocean. 

But that level of contamination doesn't seem to have been a serious problem.  So if the radiation from Fukushima only gets to that level then the overall thing isn't a big deal?
