We place a calibrated continuous radon monitor on the lowest livable level of the home and let it log hourly readings for at least 48 hours under closed-house conditions. The result is a clear average against the EPA action level of 4.0 pCi/L — no guesswork.
Radon is a colorless, odorless radioactive gas that seeps up from the soil through foundation cracks and sump pits. You can't see or smell it, which is why testing is the only way to know — add it to your 120-point inspection before you close on a Mound home.
