EDWARDSVILLE, Ill., June 23, 2026 (GLOBE NEWSWIRE) — Air Sense Environmental is urging homeowners across the St. Louis metro to test for radon this summer after the Missouri Department of Health and Senior Services reported that one in three homes in its residential testing program tested above the EPA action level of 4.0 pCi/L. In St. Louis County, average indoor radon measures 3.4 pCi/L, more than double the national average, according to Air Chek data.

Radon is a colorless, odorless gas and the second leading cause of lung cancer in the U.S., causing an estimated 21,000 deaths a year, according to the EPA. Because it cannot be detected without testing, many families remain unaware for years.
“Most homeowners are surprised the air in their basement carries any risk,” said Jake Lusby, owner of Air Sense Environmental. “A short test is the only way to know, and summer is a practical time to schedule one.”
