Assessment of Radiation Dose from the Consumption of Bottled Drinking Water in Japan

Activity concentrations of (234)U, (235)U, (238)U, (226)Ra, (228)Ra, (222)Rn, (210)Po, (210)Pb, (40)K, (3)H, (14)C, (134)Cs and (137)Cs were determined in 20 different Japanese bottled drinking water commercially available in Japan. The origins of the mineral water samples were geographically distri...

description Activity concentrations of (234)U, (235)U, (238)U, (226)Ra, (228)Ra, (222)Rn, (210)Po, (210)Pb, (40)K, (3)H, (14)C, (134)Cs and (137)Cs were determined in 20 different Japanese bottled drinking water commercially available in Japan. The origins of the mineral water samples were geographically distributed across different regions of Japan. Activity concentrations above detection limits were measured for the radionuclides (234)U, (235)U, (238)U, (226)Ra, (228)Ra and (210)Po. An average total annual effective dose due to ingestion was estimated for adults, based on the average annual volume of bottled water consumed in Japan in 2019, reported to be 31.7 L/y per capita. The estimated dose was found to be below the recommended World Health Organisation (WHO) guidance level of 0.1 mSv/y for drinking water quality. The most significant contributor to the estimated dose was (228)Ra.
