Abstract: 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.
