Comparision of several methods for the determination of the radon 222^Rn activity concentration in drinking water

In many countries, drinking water is obtained from groundwater sources such as springs, wells and boreholes. These sources of water normally have higher concentrations of radon than surface water from reservoirs, rivers or lakes. In this paper physical and chemical properties of radon and its short-lived progeny are described, as well as the mechanism of radon transfer through the soil in water and air. Some conclusions on the influence of radon and radon progeny on public health are presented. The main goal of this work is to determine the radon activity concentrations of drinking water samples and the appropriate dose due to ingestion of that water. In experimental part of this work several methods of radon measurements in water are described (alpha spectrometer, gamma spectrometer, ionization chamber and liquid scintillation detector) and results are presented. Conclusions about used methods, obtained results and discussion of the performances of all used methods are given.
