I meant radon gas not radiation gas. What Im wondering is why Uranium deposits emit radon gas. The only thing I can think of is that its created by the decay of the Uranium.
Radon is an intermediate step in the decay chains of several actinides.

U235 -

Th232 -

U238 - (at two points)

Uranium is found at low levels in the Appalacian mountains, the western mountain states, and the northern/midwestern US.

Of course, it's higher in certain deposits which are mined for the very reason that the Uranium content makes it economical to mine.
