What Is Radon and How It Impacts Your Indoor Environment


Radon exposure is the second leading cause of lung cancer in smokers and the leading cause of lung cancer in non-smokers.1 The radioactive gas is a natural decay product of uranium and can be found in almost all soils. Soil gases, including radon gas, can enter a home, build up, and put the occupants at risk. Radon gases can enter a building through several means, including:

  • Cracks and expansion joints in concrete floors
  • Water supply (through well water or other supply)
  • Cracks in basement or foundation walls
  • Openings around ground floor plumbing

How to Determine the Radon Level in Your Home

According to the EPA, “Nearly 1 out of every 15 homes in the U.S. is estimated to have elevated radon levels.”2 Since radon cannot be detected by sight or smell, a do-it-yourself test, or a short term or long term test by a qualified tester are necessary to determine radon levels. Per EPA standards, it is recommended that a home with over 4.0 pCi/L of radon in air be mitigated (or fixed).
