9. What do my test results mean?

The average indoor radon level is estimated to be about 1.3 pCi/L, and about 0.4 pCi/L of radon is normally found in the outside air. The U.S. Congress has set a long-term goal that indoor radon levels be no more than outdoor levels. While this goal is not yet technologically achievable in all cases, most homes today can be reduced to 2 pCi/L or below.

RADON AND HOME SALES

More and more, home buyers and renters are asking about radon levels before they buy or rent a home. Because real estate sales happen quickly, there is often little time to deal with radon and other issues. The best thing to do is to test for radon NOW and save the results in case the buyer is interested in them. Fix a problem if it exists so it won’t complicate your home sale.

During home sales:
• Buyers often ask if a home has been tested, and if elevated levels were reduced.
• Buyers frequently want tests made by someone who is not involved in the home sale.
• Buyers might want to know the radon levels in areas of the home (like a basement they plan to finish) that the seller might not otherwise test.
