Radon is a radioactive gas that is invisible, tasteless, and odorless, but it may be a problem in your home. Breathing the radioactive particles produced by radon is a major cause of lung cancer among non-smokers.

Testing is the only way to know if your home contains radon. Inexpensive, do-it-yourself test kits are available at home improvement stores. Free test kits are available from the County Extension Service.
