Marathon County Health Department serves as a Regional Radon Information Center (RIC) and provide technical consultation on testing for radon and how to mitigate or remove radon from the home.  The RIC serves as a resource for the Public and other Health Departments for 11 Wisconsin Counties in Northern Wisconsin. Radon is a naturally occurring, odorless radioactive gas that causes lung cancer. Between five and ten percent of the homes in Wisconsin have radon levels above the US EPA guideline of 4 pCi/L for the year average on the main floor.  Radon exposure is the leading cause of lung cancer in non-smokers.


How do I test for radon? What do I do if I have radon?

Radon testing is simple and inexpensive.  Do-it-yourself test kits can be purchased at Marathon County Health Department.  Short-term test kits are $8.00, and long-term test kits are $20.00.  Elevated radon can be reduced to safe levels by installing a radon mitigation system.  Radon mitigation should be done by trained professionals who are certified by National Radon Proficiency Program (NRPP).  Installed Radon mitigation systems usually cost approximately $1,000.
