The United States Environmental Protection Agency (USEPA) has designated January to be National Radon Action Month. They are urging homeowners, building owners and school officials to test and address elevated radon levels. Radon testing is recommended every two to three years in homes and every five years in schools and commercial buildings. Please contact us for assistance with all of your radon concerns. Environmental Doctor has five, full-time radon specialists on staff to serve you. We provide air quality tests to homes in the Dayton Ohio area.
