Abstract

In this study the radon activity concentration of water samples from the so called "Thermenlinie" are measured using two different techniques: currents measured with an ionisation chamber setup developed by H. Friedmann are compared with results obtained using a commercially available AlphaGUARD. A fit to compensate for measurements made in non-equilibrium state is applied and the detection limit is estimated.
