Abstract

Radon and radon daughter concentrations in Carlsbad Cavern are directly related to daily external air temperature minima and, to a much smaller extent, atmiospheric pressure. Conversely, more than 50% of the fluctuation in radon-induced alpha radiation at New Cave is associated with changes in atmospheric pressure, while outdoor air temperatures have no significant effect. The different effects of temperature and pressure on alpha radiation levels in the two caves are related to differences in the size and configuration of each cave.
