County rankings from actual reported radon tests
These lists rank the visible Georgia county pages by measured radon signals, not by the EPA zone label alone. Use them to spot where the state hub has a real data story before opening individual county pages.

measured counties
State-level verdict
This hub has measured high-burden counties, so the first click should be evidence-led.
The state hub is now doing a decision job: it separates first-click counties, retest counties, and lower-signal counties from 14 visible county measurement rows. 2 counties cross the high measured-burden band, so those pages should answer testing and 4.0+ action questions most directly.
First-click counties
Open Douglas County first when you need the strongest local answer. It is tagged Test-now from 47.3% 4.0+ - 5.2 pCi/L primary - 281 tests. 5 visible measured counties are elevated or high enough to review before lower-signal counties.
Buyer/seller lane
Buyer/seller lane: start with the elevated or high counties, require a fresh lowest-level test, and turn any 4.0+ property result into quote or credit math. The hub has 14 CDC-backed county rows to support that routing.
Retest lane
Retest lane: 2.0-3.9 pCi/L deserves more caution in the elevated/high county set than in lower-signal counties. The hub should send those users to county pages before product or cost paths.

Ranked by measured burden, 4.0+ share, test volume, and whether the EPA zone understates the measurement signal.
Douglas County
CDC Tracking
47.3% 4.0+ - 5.2 pCi/L primary - 281 tests
Douglas County is a first-click page: 47.3% of reported tests at or above 4.0 and 5.2 pCi/L primary result. Route no-reading users to a test now and 4.0+ users to quote or credit planning.
Hall County
CDC Tracking
39.8% 4.0+ - 4.2 pCi/L primary - 880 tests
Hall County is a first-click page: 39.8% of reported tests at or above 4.0 and 4.2 pCi/L primary result. Route no-reading users to a test now and 4.0+ users to quote or credit planning.
Gwinnett County
CDC Tracking
32.4% 4.0+ - 3.9 pCi/L primary - 3,330 tests
Gwinnett County should be opened before lower-signal counties: 32.4% of reported tests at or above 4.0 and 3.9 pCi/L primary result. It is strong enough for testing and retesting language on the hub.
Henry County
CDC Tracking
22.7% 4.0+ - 3.4 pCi/L primary - 267 tests
Henry County should be opened before lower-signal counties: 22.7% of reported tests at or above 4.0 and 3.4 pCi/L primary result. It is strong enough for testing and retesting language on the hub.

Measured pattern
Among 14 visible counties with measurement tables, 2 land in the high measured-burden band and 5 land in high or elevated measured-burden bands. That lets this hub rank counties by observed test distribution instead of repeating the EPA map.
Map vs measurements
4 elevated measured counties are not EPA Zone 1. Those are the pages where the actual test distribution matters more than a map-only answer.
Source confidence
The measured rows shown here use CDC Tracking. This is still official evidence, but the hub should keep source caveats visible until a stable state table is available.
