Radon?

Radon is a colorless, odorless, tasteless, and chemically inert radioactive gas. Radon is the number one cause of lung cancer among non-smokers, according to EPA estimates. Overall, radon is the second leading cause of lung cancer. Radon is responsible for about 21,000 lung cancer deaths every year. About 2,900 of these deaths occur among people who have never smoked.

Radon in home

Radon can easily escape from the ground into homes through floors, cracks in concrete walls, and basement drains. Levels in the home are usually higher in basements, cellars, or other structural areas in contact with soil. In closed spaces, like basements, radon can build up to relatively high levels. This is when it may pose a risk to your health.
