The radon level in my partially finished basement is from 8 to 11 pCi/L. I'm looking to have this installed professionally by contractors and the recommendation so far is to create the hole near the outside wall of the house. It seems that the recommendation is being made to make the install easier but I'm uncertain if it's most effective. I do not mind if carpet or drywall needs to be torn up.
Would I see an larger decrease in radon levels if the abatement hole was placed in the middle of the basement rather than in the corner or at the side of the house?
