Predicted: EPA radon zone

EPA Zone 3: lower predicted potential

is EPA's lowest class, and its forecast for Glades County as a whole is an average indoor of less than 2 pCi/L (less than 75 Bq/m³). A low zone clears no address in it: homes above EPA's turn up in all three zones.

Measured: tests reported to CDC

Radon tests reported for Glades County, 2008 to 2017, laboratory

CDC holds 3 reported tests for Glades County over the 2008 to 2017 laboratory totals, with a median of 1.7 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Glades County beside the counties around it is how this page reads it.

What these figures count

Only 3 tests were reported to CDC for Glades County over 2008 to 2017 (laboratory totals), and tests are often run on homes being sold or already suspected of a problem: so few describe neither the county nor this house.

Measured: CDC tracking data. Figure above: 2008 to 2017, laboratory. Measured data period: 2005 to 2017 (every CDC figure on file).

Glades County, Compared

Glades County radon figures, compared

Calculated by Radon411

CDC's largest figure for Glades County rests on 3 tests over the 2008 to 2017 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 33.3 points and no rank or comparison is drawn from it. Results reached as high as 2.4 pCi/L, with a middle value of 1.7 pCi/L.

Of the counties bordering it, 5 have a figure over the 2008 to 2017 laboratory totals: Charlotte County reported the largest share at or above 4 pCi/L, 25.3%, and DeSoto County the smallest, 4.4%, with Lee County at 25.1%, Martin County at 10.7% and Palm Beach County at 7.8% between. Farther out, St. Lucie County (53 miles away) at 0.0%, Collier County (59 miles away) at 25.9% and Indian River County (62 miles away) at 2.5% have figures too. Pooled across 62 Florida counties, 22.7% of reported tests reached that level; across every county in the country with a figure, 35.7%.

Statewide for the same period, Marion County reported the highest share (42.9%) and St. Lucie County the lowest (0.0%). EPA's 1993 map puts Glades County in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 100% of the county's land low radon potential.
