Ways to Keep Radon Levels Low Since there is no safe level of radon, reducing radon inside your home or building will always help reduce your risk of lung cancer, even when the level in your home is less than 4 pCi/L. The U.S. Department of Housing and Urban Development recommends these actions you can take to reduce your risks of lung cancer and help lower radon levels in your home:

  • Increase air flow in your house by opening windows and using fans and vents to circulate air. However, natural ventilation in any type of house is only a temporary strategy to reduce radon.

  • Seal cracks in floors and walls with plaster, caulk, or other mate­rials designed for this purpose.

  • You can cover the earth floor in crawl spaces with a high-density plastic sheet. A vent pipe and fan can be used to blow the radon from under the sheet and vent it to the outdoors
