Abstract
This study aims to measure tritium (3H) concentrations in different bottled drinking water around the world, understand the regional properties and their relation to tritium concentrations, and evaluate radiation dose from the consumption of bottled drinking water. A total of 41 different brands from 23 locations have an activities range of < 0.04–1.31 Bq L−1. The countries located in the northern latitudes have the higher observed value which is consistent with the latitude effect. There is a high chance that other control factors could also affect the activity concentration of the drinking water, such as the continental effect, seasonal effect, or human activities. The maximum annual effective dose of 1.7 × 10–5 mSv was calculated using the highest value. [ABSTRACT FROM AUTHOR]
