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

Pittsburg County, Compared

Pittsburg County radon figures, compared

Calculated by Radon411

Pittsburg County has no radon test figure of its own from CDC, whose counts over the 2006 to 2015 laboratory totals name 53 other Oklahoma counties and leave it out. Pooled across 53 Oklahoma counties, 12.6% of reported tests reached that level; across every county in the country with a figure, 36.3%.

The nearest counties with a figure are Cherokee County (80 miles away) at 32.0%, Tulsa County (83 miles away) at 6.0% and Oklahoma County (103 miles away) at 8.9%. Statewide for the same period, Delaware County reported the highest share (44.7%) and Tulsa County the lowest (6.0%).

EPA's 1993 map puts Pittsburg 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.

Pittsburg County, Geology

The ground under Pittsburg County

Predicted

USGS's geologic map puts all of Pittsburg County's mapped land in one class: low radon potential. The map puts 78.5% of Pittsburg County in the area it calls Central Oklahoma Plains and Hills and 20.9% in Ouachita Mountains, with one smaller area beside them. USGS gives the first a radon index of 7 and the second 8, both in the low band (5 to 8).
