But it actually has a much better chance of getting a lot cleaner and safer. We could start cranking out Thorium reactors and that would go a long way toward better. Did you know that burning coal releases more radiation into the atmosphere than all the nuclear accidents ever.
Denver is supposed to be more dangerous in terms of background radiation than lower parts of the country. But the main problem there is Radon gas! It is like getting 10 X-rays per year. The nice thing is that it is completely avoidable. Don't have a basement and stay out of low places where it could accumulate. The Radon is there because there is so much Uranium in the ground.
