Abstract
The influence of anthropogenic induced seismic waves on the radon potential is analysed in this study. The influence is determined near railway tracks, heavy traffic roads and on project sites. Generally, the radon concentration in soil gas increases due to vibrations, but the type of vibrations has a pronounced influence on the amount of increase. The spatial radius of radon increase is highest on project sites (D60 m). Along railway tracks the radius is wider (D30 m) than along heavy traffic roads (E25 m). The increase can be explained by a “pump effect”. That means that mechanical vibrations of mineral particles lead to an upward movement of the entire volume of soil gas. In the course of continuing vibrations the topmost layers lose radon to the atmosphere and as a result the upward transport of radon is increased. By this process radon can be pumped into houses, where it can accumulate.
