What IEMA's radon test records show for Oak Brook
IEMA publishes radon results reported by licensed measurement professionals. For test addresses in Oak Brook, we counted 1,214 valid tests on homes without a mitigation system; 37% were at or above EPA's 4.0 pCi/L action level and 13% were at or above 8.0 pCi/L.
For comparison, 42% of tests were at or above 4.0 pCi/L across the 26 DuPage-area and nearby cities we pulled from the same data, so Oak Brook is below that average. These are mostly real-estate and homeowner-ordered tests, not a random sample, so they can't predict your house — neighbors on the same block can test very differently. The only way to know is to test your own home.
Housing in Oak Brook and what it means for radon
About 8,163 people lived in Oak Brook in the 2020 Census. The median home there was built around 1979, and the biggest share of its housing went up between 1970 and 1989 (22% before 1970, 60% from 1970–1989, 11% from 1990–2009, 7% since 2010). Roughly 80% of homes are detached single-family houses and 8% are townhouses or other attached single-family homes; about 91% of households own their home.
Nearly half of Oak Brook's homes (60%) date from 1970–1989, which includes a lot of split-levels and raised ranches. Those often combine a basement slab with a crawlspace or slab-on-grade section, and a good system design accounts for both.
Next steps in Oak Brook
- If you haven't, run a short-term test in the lowest lived-in level (EPA guidance). For a home sale, use a licensed measurement professional.
- If you're at or above 4 pCi/L, get a quote from an IEMA-licensed mitigator — Illinois requires the license for paid mitigation work.
- After installation, retest to confirm the level dropped.
