Are you planning on buying or selling your home?  Things to know about Radon gas and why your home should be tested.

  • Radon is the second leading cause of lung cancer in the United States today.
  • Radon has been found in homes all over the United States, including North Carolina.
  • Wake County has moderately high radon levels with an average of 2-4 pCi/L in area homes. Radon levels > 4 pCi/L are considered unsafe.
  • Nearly 1 out of every 15 homes in the United States is estimated to have an elevated radon level.
  • Homes with radon levels > 4 Ci/L should be remediated as soon as possible to decrease levels in the home.

Homes in close proximity may have drastically different radon levels, even within same neighborhoods.

Radon can enter homes through cracks or holes in the walls and/or foundation, as well as through contaminated well water.


“Indoor radon is the second-leading cause of lung cancer in the United States and breathing it over prolonged periods can present a significant health risk to families all over the country.  It’s important to know that this threat is completely preventable. Radon can be detected with a  simple test and fixed through well-established venting techniques.” January 2005

  • All homes are at risk for high radon levels
  • Homes with or without basements and/or crawlspaces
