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.
在卢森堡瓦尔费丹格的一个废弃石膏矿中，对空气中的222Rn和220Rn浓度、大气压力以及空气样本温度进行了测量。222Rn浓度与大气压力呈负相关，与重力变化呈初步正相关。结果表明，潮汐应力会导致含氡气体在岩石-空气界面发生多孔流动。
