So long as you live in Utah, you'll always have it around. Everyone is exposed to it.

Unless you live in the basement, it's not likely that big of a deal. Long-term, chronic exposures is where you'll typically ever find any problems.

All the mitigation system is is a glorified fan with a vent (pipe extends to the outside of your house). It's up to you if you want to stall your home purchase for that.
