Radon is a naturally occurring radioactive gas. It is transparent, odorless, and tasteless.
Radon gas is produced by the natural breakdown of uranium in soil, water and rock.
Radon can enter the house in several different ways. The most common way is through soil gases that seep up through openings into the house. The soil gases will travel the path of least resistance. In this case they will take advantage of the pressure difference between the foundation and the earth's soil pressure. The gases move as if they were being pulled by a vacuum. Radon can also appear in building materials and well water, but is rare in this part of the country.
Add an answer to this item. Though maps exist showing concentrations across North Carolina (see map on the home page), the only way to determine the levels of radon in your home is to have a test done.
There are two effective types of tests, short term (90 days or less), or long term test (longer than 90 days.) Check out our section on testing for more information.
Absolutely. Radon is present in all houses, no matter the age, size, or construction style.
