But for each tU, there are 400 tons of tailing.

And when they do in situ leeching, here is what the IEA has to say about it:

« The technique of in situ leaching extracts uranium ore by percolating a solvent through the uranium bearing rock. Ammonium carbonate and sulphuric acid are common leaching agents. This technique reduces the radiation exposure of workers and avoids the creation of mine tailing heaps, but it increases the risk of groundwater contamination. Heavy metals such as cadmium, arsenic and nickel can be mobilised by the process and enter water supplies. Waste slurries and waste water from the leaching operation must be carefully handled and treated.

BTW, i know very little about all of this. I'm guessing in situ leeching produces less tailings.

Lastly, I don't get the comparison with coal-fuelled plants. I don't think it makes sense to compare the two alternatives on a step to step basis. The overall picture has to be taken into account. Arguing which alternative pollutes the less says little on which option is better for electricity generation.

And what's inert rock ("tailings") got to do with radon emissions?  Exactly nothing.

Listen, the whole point is, no matter how poor the uranium ore is going to get, it will never be as dirty as burning coal!  Those kooks with their constant "but all the damage done by uranium mining!" should get a grip on reality and rally against coal plants, because of "all the damage done by coal mining".
