<I>Uranium concentrations in some natural mineral waters sold in Japan (domestic 20 and foreign 9) were measured by ICP-MS. The</I> U <I>concentrations were found in a wide range, differing by a factor of 40000, about 0.4-1.6×10</I><SUP>4</SUP>ng/l. <I>The values over guidance level (2</I>μg/1) <I>were observed in two domestic samples and one foreign one. Occurrence of such a high</I> U <I>concentration indicates the need of further survey of</I> U <I>concentration of mineral water to consider uranium intake.</I>
