Radon Gas is a Carcinogen and is considered a national health problem. Radon is a colorless, odorless, tasteless gas that occurs naturally everywhere. Radon is present in all homes, regardless of when the home was built or what type of foundation it has. New homes and homes built on slabs are often mistaken as radon-free. The Environmental Protection Agency (EPA) recommends radon gas testing on the sale of all homes.
Radon is the leading cause of lung cancer among non-smokers and is a deadly gas emitted from decaying Uranium, entering a house through small cracks and openings. Radon gas is especially high among areas when granite is present, and Atlanta sits upon a large reserve of granite.
RIA conducts a 48 hour radon gas test utilizing a continuous monitor so results are available immediately upon retrieval of the machine. RIA conducted an analysis of radon tests completed and statistics are below. In addition, please see the diagram below of how radon enters a home. For more information on radon gas, please see more information here.
Between January 2013 and June 2016, RIA conducted over 2000 radon tests in homes around the Metro Atlanta area. Of those tests, 19% had a radon reading of 4.0 pCi/l (picocuries per liter of air) or higher. The U.S. Environmental Protection Agency (EPA) and the Surgeon General strongly recommend taking further action when the home’s radon test results are 4.0 pCi/l or greater. Based on the EPA’s classification, RIA considers results of 4.0+ as “high”.
There is a common myth that radon levels are low or non-existent depending on the foundation of the home. Based on the tests taken by RIA, there were homes with “high” radon on all types of foundations.
- Basements=24% of homes tested “high”
- Crawl Space = 8% of homes tested “high”
- Slab Homes = 4% of homes tested “high”
In addition, homes that were new construction were no less prone to come back with lower radon levels since radon is emitted from the soil and is not dependent on the age of the home’s materials.
Since only 24% of RIA’s clients elected to have a radon test completed, over 1200 families in the metro area (who completed an inspection with RIA between Jan 2013 and June 2016) likely have high radon levels and are unaware of this issue.
The EPA and Your RIA Team recommend radon testing on every home to uncover any issue with radon. The solution to high radon is the installation of a radon mitigation system and can be completed for a reasonable fee once the issue is identified.
