Zone vs. an actual test

Worth County's Zone 3 prediction undercuts the roughly 1.3 pCi/L most US homes average, nowhere near EPA's 4 pCi/L threshold for recommending mitigation. A Zone 3 label describes Worth County's average, not any one basement or slab in it — testing is still the only way an individual homeowner actually finds out.
