Radon mitigation in Springfield, IL: what to know
Radon is a colorless, odorless radioactive gas that comes from the natural decay of uranium in soil. IEMA-OHS notes that its health effect, lung cancer, usually isn't immediate, so you can be exposed for years without suspecting it. According to the EPA, radon is the second leading cause of lung cancer in the United States and is linked to about 21,000 lung-cancer deaths a year.
EPA's map puts Sangamon County, and its neighbors Menard, Logan, Morgan, Cass and Macon counties, in Zone 1, where predicted average indoor screening levels are above 4 pCi/L. That's a county-level prediction, not a verdict on your house. IEMA-OHS says homes with elevated radon have been found throughout Illinois and that all homes should be tested. See radon levels in Springfield and Sangamon County.
When to call a mitigation pro
- 4.0 pCi/L or higher: EPA and IEMA-OHS recommend reducing your radon level. IEMA-OHS estimates the lung-cancer risk at 4.0 pCi/L at about 7 deaths per 1,000 people.
- Between 2 and 4 pCi/L: EPA says consider fixing. There is no known safe level of radon.
- Buying or selling a home: Illinois sellers must give buyers radon disclosure documents. See testing during a real estate deal.
What a licensed mitigator usually does
IEMA-OHS says the most common technique is sub-slab depressurization (SSD), which doesn't require major renovations: a suction pipe goes through the slab, a fan in an attic, garage or outdoors draws the gas out, and the exhaust vents above the roof. Crawlspace homes usually get a sealed plastic membrane with suction underneath. In Illinois, a post-mitigation test must be performed to confirm the system works.
Illinois requires licensed radon pros
Under the Radon Industry Licensing Act (420 ILCS 44), no one may perform radon testing or mitigation for pay in Illinois without a license from IEMA-OHS. We only pass requests to professionals who show us a current IEMA-OHS license, and we encourage you to check it yourself on the IEMA-OHS licensee search.
