There are several ways to protect you and your family from the dangers of radon gas.
If you have an existing home with elevated levels of radon, you can fix the problem by having a radon mitigation system installed by a certified radon professional. A radon mitigation system typically consists of:
- Sealing cracks in the foundation, floors, walls, piping or other areas that are allowing radon to enter.
- Installing a vent pipe that draws radon from soil underneath the foundation and vents it outdoors – this is called a passive mitigation system.
- If extra power is needed, an exhaust fan can be connected to the vent pipe for extra power to draw radon from the soil – this is called an active mitigation system.
The type and cost of a mitigation system depends on the size of the home, house design, foundation type and other characteristics. The cost can range from $1,00 - $2,500 or more. Installing a mitigation system is an investment in your home and your health. It is always recommended to re-test your home within 24 hours – 30 days after a mitigation system is installed and every 2 years after that. Find certified radon mitigation professionals by contacting your state radon program.
If you are building a new home, ask your contractor to install radon-resistant features. These features include gravel and plastic sheeting below the foundation, sealing of cracks and the installation of a vent pipe. Once the radon-resistant features have been installed and the home is completely built, make sure to perform a radon test, as the levels could still be elevated. If the radon levels are still elevated, a radon fan should be added to the system to lower the radon level.
Detailed information about radon reduction in your home or building can be found in EPA's Consumer's Guide to Radon Reduction.
The American Lung Association is working with national partners and government agencies to build in ways to reduce radon in all homes. The National Radon Action Plan outlines strategies to protect millions more people from dangerous radon exposure.
