I'm glad the info was useful. My advice is to follow the advice on the CDC and EPA websites. Test the home, and if the guidelines suggest it, assure that
remediation mitigation work is done and maintained to reduce the risk of the occupants.
You should search the archives of the Home Improvement forum here with keyword "radon" as I recall there have been some threads where members showed pics of their remediation systems in their homes along with discussions.
Edit: The right term is "mitigation" not "remediation".
