EPA Zone 3: lower predicted potential

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

Radon tests reported for Sabine Parish, 2015

CDC holds 3 reported tests for Sabine Parish in 2015, with a median of 0.9 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Sabine Parish beside the counties around it is how this page reads it.

What these figures count

Only 3 tests were reported to CDC for Sabine Parish over 2015, 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. Figure above: 2015. Measured data period: 2005 to 2017 (every CDC figure on file).

Sabine Parish, Compared

Sabine Parish radon figures, compared

Calculated by Radon411

CDC's largest figure for Sabine Parish rests on 3 tests in 2015, 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 0.9 pCi/L, with a middle value of 0.9 pCi/L.

The nearest counties with a figure are Calcasieu Parish (93 miles away) at 0.0%, East Baton Rouge Parish (162 miles away) at 0.0% and Tangipahoa Parish (198 miles away) at 0.0%. 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 Sabine 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.

Testing a home in Sabine Parish

No CDC figure names Sabine Parish; the nearest county with one, Calcasieu Parish (93 miles away), reported 0.0% of its tests at or above 4 pCi/L over the 2006 to 2015 laboratory totals, the only reading nearby until a test of this home. Zone 3 is the lowest label, yet homes at or above 4 pCi/L occur in every zone: a short-term kit (2 to 90 days) is the quick first check in Sabine Parish.
