Why are Pennsylvania radon levels in homes so high? Indoor radon levels are dependent upon the distribution of uranium-rich rocks and soils and the porousness of the earth, near a home. Pennsylvania happens to have a high distribution of these uranium-rich rocks and soils. Different homes, even those close to each other can have varying levels of radon. These levels may be impacted by the condition of the homes, for example more foundation cracks could allow more of the gas to get into the home.
Radon is an invisible, odorless, radioactive gas that seeps into homes from the earth via cracks in the foundation or other small openings. Radon causes an estimated 15,000 to 22,000 lung cancer deaths each year. The radioactive gas is present all across the country, but Pennsylvania radon levels are exceptionally high.
Nearly every county in Pennsylvania has high radon levels. The average radon level in PA homes is around 7-8 picocuries per liter (pCi/L), while the Environmental Protection Agency (EPA) recommends that homeowners take immediate action at 4 pCi/L. The EPA says in 49 of 67 Pennsylvania counties the predicted average indoor radon screening levels exceed federal guidelines.
Because Pennsylvania radon levels for each county are different, and the variation between homes can be so drastic, homeowners should test their homes to ensure that their families are safe from radon. Contacting a certified, licensed professional to test your home if there is no mitigation technique in place or to inspect existing mitigation tools will ensure that the results are thorough and accurate.
Radon testing and inspection professionals perform two types of radon testing: short term and long term. Both forms of testing are useful. The short-term method is the most frequently used, while the long-term process most accurately represents radon levels since all seasons and many home conditions are taken into account.
Winter is a good time for testing for radon, as windows and doors mostly remain closed, allowing the testing specialist to collect data for a “worst-case” scenario. If you are planning to buy a new home in Pennsylvania, as well, you should contact the realtor to test the house for radon.
A few additional tips for testing your home for radon:
Once testing is complete, PA homeowners can decrease their home radon levels by working with a professional to install a radon mitigation system. Most radon exposure occurs in buildings, so testing and mitigation will keep more homeowners and PA residents safe and healthy.
