When was your house built?
Since the late 80's we have been roughing radon systems in new construction.
Poly under the slab, 1 pipe per 1500 SF of basement to the attic, through the roof. Only nee to add a fan.
On an older home, typically drilling a hole in the slab, PVC pipe to attic/above roof, and a fan will drop radon level.
