Radon Testing in the Metro East
Radon is a colourless, odourless radioactive gas and the second leading cause of lung cancer in the United States after smoking — and the leading cause among people who have never smoked. Most of our service area — Madison, St. Clair, Monroe, Macoupin, Bond, Clinton, Montgomery and Fayette counties — sits in EPA Zone 2, moderate potential. Jersey County is Zone 1, the highest band EPA assigns. EPA is explicit that the map is a planning tool and every home should be tested regardless of zone. A professional test uses a continuous monitor placed for at least 48 hours in the lowest lived-in level. Expect $149 to $249.
Testing is recommended for every Metro East home. A 48-hour continuous monitor with same-week results.
