Radon comes from the natural (radioactive) breakdown of uranium in soil, rock and water and gets into the air you breathe. Radon is tasteless, odorless, and colorless, and it has no warning symptoms (it does not cause headaches, nausea, fatigue, etc.). Radon enters buildings through openings in the foundation floor or walls (sump openings, crawlspaces, floor/wall joints, cracks, etc.). Radon can become trapped in buildings, and thus, lead to elevated and harmful radon levels. Exposure to long-term, elevated radon levels can increase your risk of lung cancer. According to the U.S. Surgeon General, radon is the second leading cause of lung cancer in the U.S. and results in approximately 21,100 lung cancer deaths each year.

  • For Existing Homes: Test for radon — testing is the only way to know if radon is in your home. To test your home, obtain a short-term kit from LCHD or order on online at www.mi.radon.com. For more information, call (517) 546-9858. Do-it-yourself test kits are convenient and accessible, or you may choose to have a professional test your home. If the test result indicates your radon level is too high, a qualified radon service professional can install a radon mitigation system.
  • For New Construction: Radon-resistant new construction (RRNC) draws radon from the soil and vents it through a pipe to the roof, preventing its entry into the house. This technique uses common materials and building skills. RRNC costs less than retrofitting a similar radon reduction system after the house is finished. New home buyers should ask their build to include RRNC features. All new homes, even new RRNC ones, should be tested for radon.

Radon in Livingston County

One in eight Michigan homes is likely to have an elevated radon level. According to a study conducted by the Michigan Department of Environment, Great Lakes and Energy (EGLE), radon is present in elevated levels in about 40% of Livingston County homes.

This map shows the estimated radon levels in Livingston County. These results only represent homes tested with LCHD radon test kits. Therefore, this map is not actual representation of radon levels for all homes in the Livingston County. Green areas do not ensure safe radon levels. For specific city, village, and/or township radon level maps click here.

The U.S. Environmental Protection Agency (EPA) recommends a radon mitigation system be installed in homes with radon levels > 4 pCi/L.
