Radon - Topic Overview

How do you remove high levels of radon?

If tests find a high level of radon, you'll need to reduce it. There are two parts to this:

  • Preventing radon from entering the building. The most common way to do this is through sub-slab depressurization, which vents air from beneath the foundation. This work should be done by a qualified contractor. Other control methods include sealing cracks in the foundation or walls and using air cleaners.2
  • Venting radon out of the building. Once the radon is prevented from entering the building, venting can be done to reduce the level of radon. These may include using fans, blowers, and suction devices to remove radon in the air in crawl spaces, basements, and other areas.

Use an EPA-qualified contractor with proper training in radon reduction to help with this work.

After radon reduction or prevention procedures are done, the home or building should be retested. You may need to retest more than once. It is usually safe to live in the home or building while the radon is being vented, but you may want to confirm this with your local EPA office.

For general information about removing or reducing radon in your house, you can call the Radon Fix-It Hotline at 1-800-644-6999. If you live outside the U.S., you can call your regional environmental protection office for more information.
