What is Radon? 

Radon is a naturally occurring, radioactive gas that results from the natural decay of radium, a natural decay product of uranium. Uranium is a natural part of the earth’s crust and concentrations vary from place to place. Therefore, Radon levels vary from one location to another. 

Why test? 

Radon is odorless, colorless, and cannot be detected by human senses. However, not knowing if your home has high levels of Radon can be deadly. As a carcinogen, Radon is the second leading cause of lung cancer in the United States; second only to tobacco use. 

How do I test? 

The health department offers testing kits so you can easily test Radon levels in your home. The test lasts for a minimum of 3 days, and you simply mail the kit to the address provided. Contact your local BLDHD office for a testing kit. 

How likely am I to have high Radon levels in my home? 

Geographic location is not a replacement for testing. All homes should be tested for elevated Radon levels. Environmental Protection Agency studies have found that Benzie and Leelanau counties all have potential for elevated indoor Radon levels.   

What if the Radon levels in my home are high? 

If you receive test results that show elevated Radon levels in your home, your first step should be to retest, to ensure accuracy of results. If test results continue to show elevated levels, a sanitarian can consult with you about remediation options. Click here for additional information regarding reducing indoor Radon levels.
