Home Buyer’s and Seller’s Guide to Radon
The EPA and the Surgeon General Recommend You Test Your Home
Testing is the only way to know if you and your family are at risk from radon. The EPA and the Surgeon General recommend testing all homes below the third floor for radon.
You cannot predict radon levels based on state, local, or neighborhood radon measurements. Do not rely on radon test results taken in other homes in the neighborhood to estimate the radon level in your home. Homes which are next to each other can have different radon levels. Testing is the only way to find out what your home’s radon level is.
The EPA Recommends:
- If you are buying a home or selling your home, have it tested for radon.
- For a new home, ask if radon-resistant construction features were used and if the home has been tested.
- 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.
- Take steps to prevent device interference when conducting a radon test.
U.S. Surgeon General’s Health Advisory
“Indoor radon gas 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.”
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 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.
If you are having a new home built, there are features that can be incorporated into your home during construction to reduce radon levels.
These radon testing guidelines have been developed specifically to deal with the time-sensitive nature of home purchases and sales, and the potential for radon device interference. These guidelines are slightly different from the guidelines in other EPA publications which provide radon testing and reduction information for non-real estate situations.
This guide recommends three short-term testing options for real estate transactions. The EPA also recommends testing a home in the lowest level which is currently suitable for occupancy, since a buyer may choose to live in a lower area of the home than that used by the seller.
