Radon

Radon is a colorless, odorless, tasteless, and radioactive gas that originates from the ground. Learn about the risks it poses, how to test your home for it, and how to fix or mitigate high radon levels.

Radon is a carcinogen, which means it is known to cause cancer in humans. While there are many sources of radiation, radon remains the largest source of exposure. Because we spend so much time indoors, radon in the home represents the biggest exposure and concern.
