- Natural radioactivity has been measured in 22 different bottled waters from central and southern Poland. Although most of the investigated waters originate from the Outer Carpathian Mts. (Flysch Carpathians), samples from the Krakow-Częstochowa Upland, Lublin Basin, Podlasie Depression, Silesian-Krakow Monocline -Lodz Basin and Sudety Mts. were also analysed. Mineralization of these waters is dominated by the HCO), Ca2+, Mg2+, Na+ ions andfalls within the range from 186 mg/l to 2930 mg/l. Except for "Staropolanka 2000" and "Wielka Pieniawa", the activities of radium isotopes in all other waters are in the order of several mBq/l, with the maximum values reaching 100 mBq/l. The activities of uranium isotopes are below 75 mBq/l, with the average values of 4.9 mBq/l and 11.7 mBq/l for 238U and 234U, respectively. The calculated annual committed effective dose from uranium and radium isotopes resulting from the consumption of the investigated waters by teenagers and adults is lower than the recommended value of 0.1 mSv/year. However, if some of the analysed waters ("Dobrawa", "Nalqczowianka", "Polaris", "Aquarel", "Hermes", and highly mineralized waters) are used to prepare food for infants below 1 year old, then the annual committed effective dose will exceed the recommended value.
