Effect of atmospheric pressure variations on the 222Rn activity concentration in the air of a wine cellar

We have measured the variation of atmospheric pressure and of 222 Rn activity concentration in the air of a wine cellar with an AlphaGAURD type ionization chamber radon monitor. We have found that the 222 Rn activity concentration varies inversely with pressure. To explain this behavior we have done...

Zusammenfassung:We have measured the variation of atmospheric pressure and of 222 Rn activity concentration in the air of a wine cellar with an AlphaGAURD type ionization chamber radon monitor. We have found that the 222 Rn activity concentration varies inversely with pressure. To explain this behavior we have done model calculations. We have compared the results of model calculations with the results of experimental measurements, and we have found that the model is capable to reproduce some part of the variation of 222 Rn activity concentration.
