La Grange Park, IL Radon Facts
This well-established Cook County suburb features predominantly single-family homes built between the 1920s and 1960s, most with full poured-concrete basements. While specific radon data for the 60526 zip code is currently limited, the Chicago Metro's glacial till deposits over limestone bedrock create conditions highly favorable for radon accumulation. Homeowners should prioritize testing, as the area's enclosed basement spaces and older foundation materials can facilitate radon entry and concentration.
Cook County average: 6.44 pCi/L, based on 82 user-submitted tests across 40 cities in the county. No homeowner readings have been submitted for La Grange Park itself yet, so this county figure is the closest available benchmark. The EPA recommends taking action at or above 4.0 pCi/L.
