How does your state measure up in their

Risk and Response to radon?

The purpose of the AARST Radon Report Card is to facilitate evaluation and rating of state radon policies and risk. AARST anticipates that this resource will assist consumers, policy makers, public advocates, soil gas professionals, radon programs, researchers, and others in expanding and improving efforts to stop radon in homes, schools, and other buildings.
