Radon


What is radon?

Radon is a tasteless, colorless, and odorless radioactive gas.

Radon is formed by the natural decay of uranium in soil and rock.


Radon moves through the ground and enters your home through:

  • Cracks
  • Sump pump pits
  • Crawl spaces
  • Other holes in the foundation.

Your home traps the radon inside, where it can build up to unsafe levels. Radon is also found in outdoor air, but it is diluted to such low levels that it’s usually not a concern.

Why is radon considered a health risk?

When you breathe radon gas, tiny radioactive particles are trapped in your lungs, damaging the lung tissue.

Over time, this tissue damage can lead to lung cancer.

  • Radon is the second-leading cause of lung cancer in the United States, and is associated with over 20,000 lung cancer deaths each year.
  • Not everyone who breathes radon will develop lung cancer, but your risk is greatly increased if your home has high levels of radon, and if you smoke or live with someone who smokes.


What is considered a safe level of radon?

Radon is measured in “picocuries per liter,” which is a unit of measurement for radioactive materials. Although there is no “safe” level of radon, the Environmental Protection Agency (EPA) recommends taking action to reduce radon levels above 4.0 pCi/L.

  • To put this into perspective, the average indoor radon level in the United States is 1.3 pCi/L, and the average outdoor radon level is 0.4 pCi/L.

Michigan Indoor Radon Results Web Map

Published: November 21, 2023. EGLE created this map to show the radon information for first time tests, without active radon mitigation systems, by ZIP code. This map is based on results from the supplier that manufactures and analyzes short-term radon test kits purchased through the EGLE radon program.
