Radon is an odorless, colorless gas and the second leading cause of lung cancer in the United States. In Olmsted County, our karst geology and long, cool seasons can draw more radon into homes, increasing the likelihood of elevated indoor levels. Because radon cannot be seen or smelled, testing is the only way to know if your home is safe. 

Olmsted County is sharing a new short video to help residents understand radon risks and learn how to complete a simple short‑term radon test. 

This video covers:  

  • What radon is and how it enters homes. 
  • Why Olmsted County’s geology can increase radon levels. 
  • How to order, set up, and return a radon test kit. 
  • Tips for accurate testing.
