When analyzing the total annual effective dose from natural sources to human population the dose received by ingestion of long-lived natural radionuclides needs consideration. Doses by ingestion are mainly due to 40K and to the 238U and 232Th series radionuclides present in food and drinking water. In South America the human water-supply is based in networks and domestic wells thatuse water from aquifers, consequently more than the 60% of the population drinks untreated water. In this frame, we present here the results of a systematic study of the gamma emitter content of drinking water samples consumed at the Province of Buenos Aires- Argentina.
