Radon and Your Health

Radon can cause lung cancer

Radon can lead to lung cancer after many years of breathing it. Radon is the leading cause of lung cancer among non-smokers and the second leading cause of lung cancer overall. The most important thing you can do is to test your home and find out if your home has high levels of radon.

The United States Environmental Protection Agency (EPA) and the U.S. Surgeon General strongly recommends all homes be tested for radon. Homes with radon levels of four picoCuries per Liter (4 pCi/L) or higher should be fixed.

3 factors affecting lung cancer:

  • Amount of radon in your home
  • Amount of time spent in your home with radon
  • Your smoking status

Smoking combined with radon is a serious health risk

The best way to reduce your risk of lung cancer is to stop smoking and lower your radon levels. Protect yourself from radon exposure and get help to quit smoking.
