Healthy Homes: Radon

You can’t see, smell, or taste radon but exposure to radon is the second leading cause of lung cancer in the United States. In Iowa, 72% of homes have high radon levels (above 4pCI/L).

What is radon?

Radon is a naturally occurring, radioactive gas that can build up in your home and can cause cancer. Radon usually comes from the soil and can enter your home through any openings on the lower levels of your home, including cracks or sump pump openings.

Radon testing is easy and inexpensive:

  • Purchase a test for $10 at your city office or Community Health Partners in Orange City
  • Test your home for radon every 3-4 years during the winter months (January, February, or March).
  • All homes should be tested, including new homes, since newer homes are more airtight.

What if my home has a high radon level?

Homes with high radon levels should be fixed. See for more information.
