The EPA maps Middlesex County as radon Zone 1: counties where the predicted average indoor radon screening level is above 4 pCi/L — over the EPA action level. Radon is a naturally occurring radioactive gas and the second-leading cause of lung cancer in the US; in Zone 1 counties, testing before finalizing a purchase (and asking about mitigation systems) is standard advice. The zone is a county-scale prediction from geology, aerial radioactivity, soil, and past measurements — not a measurement of this home. Radon varies house to house; a short-term test kit (about $15–30, or often free from state health programs) is the only way to know this home's actual level.
