Or other fracking-adjacent risks like microearthquakes.
Are these really that much of a problem if the wells are far from urban areas?
if they are too far away you'd have a loss of efficiency since I guess they'll transfer heat and not current, no?
Not significantly if you are say 100km away.
Uranium and Thorium decomposes into Radium, which themselves are found at 450m but the gas then rises through the Earths crust as it moves. I could see this kind of constant agitation releasing significantly more at least within a radius.
