Indeed, while I don't have specific numbers to prove this, I highly suspect that the health risks of non-nuclear toxic waste (by products from chemical plants and manufacturing) outweigh those of toxic nuclear waste and the release of these chemicals are often far less regulated than nuclear waste.

I not saying that nuclear is the future, but it is a important amd relativly safe source that we can use as stop gap to limit our use of more dangerous power sources while we fight global warming and find safer and cleaner sources of energy. We need to consider all of the risks of our power sources and not spread misinformation and fear.

Gulf war syndrome is another example of head-in-the-sand behavior of the public regarding nuclear waste caused diseases.
