In the U.S., an estimated 21,000 people die from radon-related lung cancer every year. Compare that number to 160,000 lung cancer deaths from smoking, radon is responsible for almost ⅛ of all lung cancer deaths.

Radon is the second-leading cause of lung cancer, and it’s the leading cause of lung cancer in non-smokers, according to the EPA.

There is an elevated risk of radon exposure in all of Western North Carolina and an even higher risk in Buncombe, Henderson, Transylvania, and Cherokee Counties. This includes the highly populated areas of Asheville and Hendersonville.

As there are no immediate symptoms that will alert you to the presence of radon, testing is the only way to know the radon levels in your home.

The US EPA, Surgeon General, American Lung Association, American Medical Association, and National Safety Council recommend testing your home for radon.

What Can You Do?

Yes, the above information is concerning and an unfortunate part of living in our mountainous area. On the bright side, if a home is tested and radon levels are found to be high, this problem can be addressed.

The first step is finding a trained and reliable technician who uses a dependable, accurate monitoring system. Land of Sky Home Inspections ticks all of those boxes. Land of Sky Home Inspections is trained by the International Association of Certified Home Inspector (InterNACHI), through a course accredited by the US Department of Education. Additionally, we use professional-grade radon monitors which are approved by The National Radon Proficiency Program (NRPP) and The National Radon Safety Board (NRSB).

Secondly, once your home has been tested for the presence of radon and your inspector has shared the results it may be time for the next steps. According to the EPA, the average concentration must be 3.9 picocuries/liter or less to be at an “acceptable” level. If the results are 4.0 picocuries/liter or higher, mitigation is recommended.

If your results come back high, this can be addressed. Oftentimes, for around $1,500, a radon mitigation system can be installed below the slab foundation. A fan helps to depressurize this area and vents gasses beneath the home to the outside. It is typically a simple process, but it is very important that you have a qualified professional handle the mitigation process.
