title: Measurements of radon concentration and the role of earth tides in a gypsum mine in Walferdange, Luxembourg.
abstract: Measurements of the 222Rn and 220Rn concentration in air, the atmospheric pressure, and the air sample temperature were carried out in an abandoned gypsum mine in Walferdange, Luxembourg. The 222Rn concentration shows a negative correlation with the atmospheric pressure and a tentative positive correlation with gravity variations. The results suggest a porous flow of radon bearing gas across the rock-air interface, which is induced by tidal stresses.
