Zone vs. an actual test
At Zone 3, Rogers County's predicted county average is under the national indoor average (~1.3 pCi/L) and well below EPA's 4 pCi/L action level — outdoor air nationally runs about 0.4 pCi/L for comparison. A Zone 3 label describes Rogers County's average, not any one basement or slab in it — testing is still the only way an individual homeowner actually finds out.
Testing and mitigation in Rogers County
