I think uranium at that concentration would qualify your lot as a Superfund site. It's a toxic heavy metal and that's a lot. Your numbers might be off by a zero or two.
As others have pointed out here, no, I was not off. It's a bit of a shocker to realize how much U is out there. There's a reason one should test your basement for radon before you buy a house.
Of course. The point is that if a nation wants to make nuclear weapons, keeping them away from uranium is a nonstarter. Uranium is everywhere, if you're willing to pay to extract it (in this case, by piling up the dirt and leaching the uranium using a bicarbonate solution).
Fun fact: if the uranium and thorium in an average crustal rock were totally fissioned (using breeder reactors), the rock would produce about 20x the heat energy of burning the same mass of coal.
