| Abstract: | Usage of the radon flux density at the Earth’s surface as an indicator of seismic activity is proposed in addition to unit-volume radon activity in the soil air that has previously been used for this purpose. Numerical calculations based on the diffusion-convection equation for radon transport in porous media are presented, which confirm that the radon flux density is more sensitive to changes in convection rate than unit-volume radon activity. It has been indicated that the advantage in using radon flux density could be greatest for homogeneous geological media. |
