The lower the radon levels in your home, the lower your family's risk of lung cancer. The amount of radon in the air is measured in picocuries per liter (pCi/L). The U.S. Environmental Protection Agency (EPA) recommends fixing your home if the results of one long-term test or the average of short-term tests show radon levels of 4 pCi/L or higher. You may also want to consider fixing if the level is between 2 and 4 pCi/L. Review the test results for each home. Calculate the average of each pair of readings and determine whether the homeowner should consider fixing the home.
