There's a killer lurking in and around your home and you may not even know it. Dead bolts and window locks are no match; in fact you could be in danger right now!

That killer is Radon, a radioactive gas. It's a deadly by-product of decaying Uranium in the ground.

How deadly? Consider this; Radon is responsible for more than 20,000 lung cancer deaths every year. Claiming more lives annually than drunk driving and house fires, combined!

According to the surgeon general, Radon exposure is second only to smoking as the leading cause of lung cancer in the U.S. Scary! When you consider more people who've never touched a cigarette are developing lung cancer. According to Dr. Veena Antony for those who do smoke Radon only increases their risk of getting it.

Your home could pose a threat to your health without you even knowing it.

Radon is estimated to cause thousands of lung cancer deaths in the U.S. each year.

A potential killer could be lurking in your home.

Kevin Siers, Radon Mitigation Contractor says, "that's the bad thing about radon. There are no warning signals."

Siers tests for the radio-active gas in homes around the Mid-Ohio Valley.

He says, "radon is a gas that comes from decaying uranium under the soil."

Most people only test when buying or selling a home, but the Environmental Protection Agency suggests otherwise.

Siers adds, "we all should get our homes tested for radon every 2 years as the EPA suggests."

Testing is simple: It takes anywhere from two to 90 days. The contractor simply comes to your home, sets up the radon detector, and comes back for the results.
