Nowadays the consumption of bottled mineral waters has become very popular. The average consumption of these is 0.36 l d–1 per person in Europe. A considerable segment of the population drinks almost only mineral water as drinking water, which is about 1 l d–1. As is known, some kinds of mineral waters contain naturally occurring radionuclides in higher concentration than the usual drinking (tap) water. The WHO (1993) legislation concerning the drinking waters does not include the mineral waters. In our work, the concentrations of 226Ra, 238U and 210Po were determined in mineral waters available in Hungary. To determine the 226Ra concentration the emanation method was used. The 238U and 210Po concentrations were determined by alpha spectrometry using semiconductor detector. The dose contribution was calculated using the radionuclide concentrations and the dose conversion factors from the Basic Safety Standard IAEA (1995), for 1 l d–1 mineral water consumption. In some cases the calculated doses were considerable higher than the limit for drinking waters. Especially for children the doses can be remarkably high.
