Radon is present in the brine that is mixed with fracking fluids that return to the surface after injection at shale gas wells ( This article refers to the Marcellus deposit in NY State as well as one in Texas, but there are many wells in the midwest that should be similar. According to this, higher radiation on a sensor lowered into the wells is used to detect the depth of the shale layers, because radioactive elements tend to concentrate in living organisms which are the original source of the oil/gas. Decay into soluble Radon puts it into the ground water at that layer, and mixing with the injected fluids can bring it up to the surface.

Has anyone brought a geiger counter to tailings ponds? Is it possible that the short-lived spikes we are seeing are due to drilling/fracking activity at upwind fields? Shale wells are at

I believe there are several possible sources for our elevated readings from time to time. This is why it's so important that more people set-up their own outside units connected to NETC. By tracking the readings from station to station we all have a better chance to determine the source. At the very least the station operators with have an immediate alert of elevated radiation levels and they can avoid being outside as a precaution. When or if the isotopes are identified, personal exposure to them have already taken place. I assume all elevated levels are the really bad stuff. Better to be safe than sorry.
