According to the EPA, radon causes approximately 21,000 lung cancer deaths per year and is the second leading cause of lung cancer behind smoking. More people in the US die from radon than from drunk drivers, homicides or Parkinson's disease.
What is radon? Radon is a gas that results from the breakdown of Uranium in the soil. It most often gets into a home through cracks in the foundation or construction joints as the gas moves up through the ground. Radon cannot be seen or smelled – the only detection method is testing.
Radon exists in every state and approximately 6% of all houses have elevated levels. High radon levels have been found in every state and can vary from house to house. In addition, there is no safe level of radon.
