Characterisation of222Rn concentrations in Lithuanian spa waters and comparison of the measured radon concentrations in spa waters with those in ground waters with a small content of mineral salts and in waters from private wells were the objectives of this study. The measurements were performed in 34 spa water sources in four different places of Lithuania using the liquid scintillation method with a Packard Liquid Scintillation Analyser Tri-Carb 2770 TR/SL and the Packard BioScience cocktail. Techniques of222Rn extraction from water samples with a high mineralization to toluene in order to exclude precipitation in a mixture with organic scintillation cocktail are discussed. Results of comparison of the two methods—liquid scintillation counting and that using E-PERMS® system electrets—are also presented. [ABSTRACT FROM AUTHOR] |
