Yes. Radon is a radioactive gas that seeps in from the soil beneath a home and is a leading cause of lung cancer, while mold spores are microscopic and become a health concern when moisture allows them to grow and spread indoors. Both are common contributors to poor indoor air quality, and both require dedicated testing and mitigation, which is why Ensign addresses radon, mold, and general air quality together as part of a whole-home approach.
