It rises.

Right.

So as heat goes up in your house, it creates a positive air pressure upstairs.

Yeah.

And a negative air pressure in the lowest level.

That little gap.

That's where the radon's all being sucked in.

But the problem is we can't see it.

I get that question all the time.

So it's a geological lottery.
