Predicted: EPA radon zone

EPA Zone 3: lower predicted potential

is EPA's lowest class, and its forecast for Cameron 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 Cameron Parish, 2008 to 2017, laboratory

CDC holds 1 reported test for Cameron Parish over the 2008 to 2017 laboratory totals, a result of 0.1 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Cameron Parish beside the counties around it is how this page reads it.

What these figures count

Only 1 test was reported to CDC for Cameron Parish 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 parish nor this house.

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

Cameron Parish, Compared

Cameron Parish radon figures, compared

Calculated by Radon411

CDC's largest figure for Cameron Parish rests on 1 test over the 2008 to 2017 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 100.0 points and no rank or comparison is drawn from it. Results reached as high as 0.1 pCi/L, with a middle value of 0.1 pCi/L.

Calcasieu 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, East Baton Rouge Parish (134 miles away) at 0.0%, Tangipahoa Parish (175 miles away) at 0.0% and Jefferson Parish (184 miles away) at 1.5% 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 Cameron 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.
