What is radon?

Radon is a carcinogen, a deadly carcinogen leading to lung cancer. Radon has been determined to be the second leading cause of lung cancer, so the effects of radon are deadly. Radon comes from the breakdowns of radium which is found in most soils. This radioactive breakdown enters buildings through the foundation typically and can be trapped inside the house. Indoor radon levels will test higher because of the concentration of the gases as they are trapped indoors.

Radon Facts and Myths

MYTH #1. My home is new so I don't have a radon problem.

Fact: This is simply not true. New homes can have just as much radon inside as an older home and sometimes even more depending on how tight the house is built.

MYTH #2. My neighbor doesn't have high radon levels so my house won't either.

Fact: This is also not true. Your home could have twice as much radon as your neighbors home. This depends on if your house has a crawl space how tight it is, cracks in the floor, open sump lids etc...

MYTH #3. Radon isn't really harmful, I've lived here for 25 years and don't have any health problems.

Fact: The truth is that radon is the leading cause of lung cancer in non-smokers. Only people that smoke have a higher risk of getting lung cancer. You will reduce the risk of lung cancer when you reduce the radon levels, even if you have lived with an elevated radon level for a long time.
