Radon soil gas measurements in a geological versatile region as basis to improve the prediction of areas with a high radon potential.

With the aim to predict the radon potential by geological data, radon soil gas measurements were made in a selected region in Styria, Austria. This region is characterised by mean indoor radon potentials of 130-280 Bq m(-3) and a high geological diversity. The distribution of the individual measuring sites was selected on the basis of geological aspects and the distribution of area settlements.

Radon in waterworks: dose assessment, analysis of influence parameters and improved methods of measurement.

In Austria a comprehensive study on radiation exposure in waterworks was conducted. The aim of this study was to evaluate the risks for the affected employees. On the basis of geographical, geological and hydrological aspects, 21 waterworks were selected.
