EPA Zone 3: lower predicted potential

is EPA's lowest class, and its forecast for East Feliciana Parish 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 East Feliciana Parish, 2005 to 2014, laboratory

CDC holds 2 reported tests for East Feliciana Parish over the 2005 to 2014 laboratory totals, with a median of 1.1 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). East Feliciana Parish beside the counties around it is how this page reads it.

What these figures count

Only 2 tests were reported to CDC for East Feliciana Parish over 2005 to 2014 (laboratory totals), and tests are often run on homes being sold or already suspected of a problem: so few describe neither the parish nor this house.

Measured: CDC tracking data. Measured data period: 2005 to 2014.

East Feliciana Parish, Compared

East Feliciana Parish radon figures, compared

Calculated by Radon411

CDC's largest figure for East Feliciana Parish rests on 2 tests over the 2005 to 2014 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 50.0 points and no rank or comparison is drawn from it. Results reached as high as 1.2 pCi/L, with a middle value of 1.1 pCi/L.

East Baton Rouge Parish, the one bordering county with a figure over the 2006 to 2015 laboratory totals, reported 0.0% of its tests at or above 4 pCi/L. Farther out, Tangipahoa Parish (41 miles away) at 0.0%, Jefferson Parish (91 miles away) at 1.5% and Calcasieu Parish (144 miles away) at 0.0% have figures too. Pooled across 37 Louisiana counties, 2.8% of reported tests reached that level; across every county in the country with a figure, 36.3%.

Statewide for the same period, Jefferson Parish reported the highest share (1.5%) and Tangipahoa Parish the lowest (0.0%). EPA's 1993 map puts East Feliciana Parish 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.
