The data

Predicted: EPA radon zone

EPA Zone 3: lower predicted potential

is EPA's lowest class, and its forecast for Pike 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.

USGS geologic potential: Low across 92% of the county's area

Measured: tests reported to CDC

No CDC test figures here

CDC has published no radon test figures for Pike County. Garland County, 41 miles away, is the nearest county with a figure over the 2007 to 2016 laboratory totals.

How to read these figures

Pike County, Compared

Pike County radon figures, compared

Calculated by Radon411

No CDC figure names Pike County, in any year or ten-year total; over the 2007 to 2016 laboratory totals, the agency's counts reach 60 Arkansas counties without it. Pooled across 60 Arkansas counties, 22.7% of reported tests reached that level; across every county in the country with a figure, 35.8%.

The nearest counties with a figure are Garland County (41 miles away) at 45.8%, Saline County (65 miles away) at 31.9% and Pulaski County (87 miles away) at 6.8%. Statewide for the same period, Garland County reported the highest share (45.8%) and Pulaski County the lowest (6.8%).

EPA's 1993 map puts Pike County in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 92% of the county's land low radon potential.

Pike County, Geology

The ground under Pike County

Predicted

Most of the ground under Pike County is one class on USGS's geologic map: 92.0% of its land is low radon potential, with 8.0% moderate. The map puts 58.6% of Pike County in the area it calls Athens Plateau/Fourche Mountains and 33.4% in West Gulf Coastal Plain, with one smaller area beside them. USGS gives the first a radon index of 8 and the second 7, both in the low band (5 to 8).

Pike County, Cities and towns

Cities and towns in Pike County

About 9,964 people live in Pike County by the Census Bureau's estimate for July 1, 2025, 194 fewer than in 2020 (−1.9%). That works out to 17 people per square mile of land. Glenwood, the largest place on its list (2,016 residents in all), extends beyond Pike County, so no share of the total is worked out for it. CDC publishes no radon test count for Pike County; across Arkansas its counts for 2007 to 2016 come to 0.2 tests for every 1,000 residents (2025 estimate).

From Glenwood to Daisy, CDC publishes no figure by town: each reads Pike County's.
