Marcellus Shale is 8 to 32 times background. This compares to an average radium-226 in
surface soil in New York State of 0.81 picoCuries per gram (pCi/g)5
Using this range of radium concentrations and a simple Fortran program that simulates
the production of radon in the well bore, and transit to the wellhead, we calculate a range
of radon concentrations at the wellhead between 36.9 picoCuries per liter (pCi/L) to 2576
These wellhead concentrations in Marcellus shale are up to 70 times the average in
natural gas wells throughout the U.S. The average was calculated by R.H.Johnson of the
US Environmental Protection Agency in 1973 (pre-fracking) to be 37 pCi/L6 to a
maximum of 1450 pCi/L.
Somehow the range, from the same as other gas to under twice the amount of other gas, becomes up to 70 times the concentration. By comparing the lowest part of one range with the highest part of the other.
That\’s a really rather remarkable use of statistics. Entirely and absolutely true in detail and entirely and completely misleading overall.
Far more accurate would be to sway that fracked gas from the Marcellus has up to twice the radon content of other natural gas.
That may or may not be a problem what with radon exposure most certainly being capable of producing lung cancer. But that is what the problem is.
