What is Radon gas?  Back

  • Radon is a radioactive gas released during the natural decay of uranium the soil.  Radon is odorless and invisible.
  • Radon gas is the 2nd leading cause of lung cancer and is estimated to cause 14,000 deaths per year, according to the National Safety Council. 
  • Radon enters a home through cracks in floors and walls, floor drains, drain systems and sump pits, construction joints, and exposed soil in crawlspaces.  Homes with well-water can develop radon concentrations through showering and doing laundry.
  • The EPA, the Surgeon General, the American Lung Association, and the American Medical Association recommend testing for radon gas as a health precaution. 
  • The EPA recommends radon mitigation if the concentration level is 4.0 picocuries per liter (pCi/L) or higher.
  • Many corporate relocation companies require testing for radon gas prior to home purchase, and require mitigation if the concentration exceeds the acceptable threshold. 
  • Homes with elevated radon levels can usually be corrected for less than $1,000.
