Radon Testing
Home Buyer's and Seller's Guide to Radon
Radon is a dangerous gas that emits from the ground, and can become problematic without proper mitigation measures. Give your family peace of mind with a professional radon test before your home purchase. The EPA recommends...
- If you are buying a home or selling your home, have it tested for radon.
- Fix the home if the radon level is 4 picoCuries per liter (pCi/L) or higher.
- Radon levels less than 4 pCi/L still pose a risk, and in many cases, may be reduced.
If You Are Selling a Home...
The EPA recommends that you test your home before putting it on the market and, if necessary, lower your radon levels. Save the test results and all information you have about steps that were taken to fix any problems. This could be a positive selling point.
If You Are Buying a Home...
The EPA recommends that you know what the indoor radon level is in any home you are considering buying. Ask the seller for their radon test results. If the home has a radon-reduction system, ask the seller for information they have about the system.
If the home has not yet been tested, you should have the house tested.
Why do you need to test for radon?
Radon has been found in homes all over the U.S.
Radon is a radioactive gas that has been found in homes all over the United States. It comes from the natural breakdown of uranium in soil, rock and water, and gets into the air you breathe. Radon typically moves up through the ground to the air above, and into your home through cracks and other holes in the foundation. Radon can also enter your home through well water. Your home can trap radon inside.
Any home can have a radon problem, including new and old homes, well-sealed and drafty homes, and homes with or without basements. In fact, you and your family are most likely to get your greatest radiation exposure at home. That is where you spend most of your time.
Nearly one out of every 15 homes in the United States is estimated to have an elevated radon level (4 pCi/L or more). Elevated levels of radon gas have been found in homes in your state.
