How effective is radon mediation when the house is testing at 9.7?
9.7 where. If that's in the basement, you might have success. It that

Age of house plays a factor, too. Newer ones are tighter.
You don't happen to have a drainage system under your slab, do you?
Do you have a basement or a crawl space or what?
