Yeah it's only because you might spend less time in the basement. In fact they tend to be the worst because they often capture the gas through the sumps and other intrusions, and tend to be less well ventilated. Moreover radon, in North America, is worse in places that build with basement more often (due to lower frost lines). My understanding is that radon comes from uranium rock fragments that were transported down from the arctic via glacier movement.
