Radioactivity assessment and lifetime risk survey from bottled water in Iran

In the last few years, tendency to utilization of bottled water has significantly expanded. Therefore, its radioactivity level must be strictly evaluated. This work aims measure activity concentrations gross beta and alpha in drinking evaluate quality annual effective dose as well lifetime risk. The 30 mineral samples from several brands was analyzed with Wallac Quantulus 1220 LSC. measurement results showed that ranged 29 49 mBqL-1 an average 38.7 48 76 60.8 respectively. Furthermore, Annual doses 30.11 48.3 µSv y-1 value 38.54 y-1, which is below 0.1 mSv y−1 reference limit. variation risk 1.70 × 10-4 2.60 2.14 10-4. According this study’s results, radiologically, these waters can considered safe Iran.
