Berkeley, IL Radon Facts
Located in Cook County within the Chicago metro area, Berkeley sits atop glacial till deposits that can facilitate radon migration from underlying limestone bedrock. The community's predominantly mid-century housing stock features full basements typical of the region, creating enclosed below-grade spaces where radon can accumulate. With limited local testing data available, residents should conduct radon measurements to understand their individual home's radon levels.
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 Berkeley itself yet, so this county figure is the closest available benchmark. The EPA recommends taking action at or above 4.0 pCi/L.
