Interpreting the Test Results

Radon is measured in picocuries per liter [pCi/L]. Levels at or above 4 pCi/L should be reduced through mitigation. For more information on reducing levels of radon in your home, request a copy of the EPA Consumers Guide To Radon Reduction, “How to Reduce Radon Levels in your Home” or contact RTCA® for guidance.
