Daily? Odd unit given Fukushima was over a decade ago. Also, "extracting" gas would compare to mining uranium from the ground, not to running a plant.

I'm only finding US statistics for the "extracting" part, and that looks like about 1000 dead in just the USA, just with regard to oil and gas extraction, in the last decade.

But, given your style and the newness of your account, I find it very hard to trust that you're really "just curious", rather than using the phrase to create rhetorical affect.
