Radon

Radon is a radioactive gas that comes from the ground. Learn about the risks it poses, how to test your home for it, how to fix high radon levels, and what guidance is available.

Radon is known to cause cancer. 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 concern. The Massachusetts Department of Public Health (DPH) recommends all homes and schools be tested for radon.
