200 years vs. 70 years. IDK if this is comparable. Also it is so that with nuclear accidents theres a lot of additional environmental damage, not just the human casualties.
Not defending coal mining here, coal is no good energy source by all means.
Coal is often radioactive when it comes out of the ground, and thanks to poor regulations, is often radioactive when it goes into the powerplant, leading to radioactive particles coming out of the smokestacks and landing anywhere downwind of the plants.
More people have died from radiation poisoning from coal than from all of the nuclear accidents combined. But, as you said, 200 years vs. 70 years. But, also, nuclear is much more heavily regulated than coal in this regard due to the severity of those accidents. The risk of a dangerous nuclear power plant is nowhere near as large as commonly believed. It doesn’t take long to find longlasting environmental disasters due to fossil fuels, from oil spills to powerplant disasters. They’re used so heavily that it’s just so much more likely to occur and occur more often.
All this to say that fossil fuels suck all around and we should be looking at all forms of replacement for them, nuclear being just one option we should be pursuing alongside all the others.
