Since Sieverts are a measure of ionizing radiation, then obviously the background levels I mentioned are ionizing radiation.

Certainly the physical distribution of the radiation sources are important, but I didn't think that was worth mentioning in a simple summary comparison. Sieverts already attempt to correct for biological effects, but yes, if the radiation source is something that can internally bioaccumulate, it will have more complex and serious effects. That is beyond a simple single-measurement comparison, however.

Solar is dead. Most of the US doesn't get enough sun to make solar feasible.

This article has a good solar efficiency study for the entire US. In summary, there's not a lot of difference in the contiguous US - about the only place where solar is significantly worse off is Alaska.

As long as we're going to reinvent the wheel again, we might as well try making it round this time. - Mike Dennison
