 Kemling Cave is located in Dubuque County, Iowa.  It is a single-entrance cave with 3.51 km of surveyed passage.  The entrance is gated, but done so in a manner that does not impede air exchange between the cave and the surface environment.  Past work has shown that measurement of radon activity as a function of time in this cave displayed an extreme degree of variability.  In this work, follow-up studies were designed and carried out to measure radon activity in parallel with a number of other environmental parameters, seeking to find which of the parameters had the strongest correlation with the radon activity.
