Introduction: Radon 222 is a natural radioactive element with a half-life of 3.8 days. It is odorless and colorless as well as water-soluble. Consuming waters which contain high concentrations of 222Rn would increase the effective dose received by different age groups. It would also be followed by an increased prevalence of cancer.
Methods: In this research, 72 samples of the most commonly used bottled water in Bandar Abbas were collected in 3 consecutive months May, June and July of 2013. 222Rn concentration was measured by means of a radon-meter model RTM166-2 made. The effective dose received by the 4 age groups, male and female adults as well as children and infants was estimated using the equation proposed by UNSCEAR.
Results: The results revealed that the mean and range of 222Rn concentration in bottled waters were 641±9 Bq/m3 and 0-901 Bq/m3, respectively. The mean concentration of 222Rn in the well-known trademarks followed this BW4> BW2> BW8 > BW1> BW6> BW3> BW5> BW7.
Conclusion: The annually received effective dose of 222Rn from the most commonly used trademarks of bottled water in Bandar Abbas was lower than the standard limit (0.1 mSv/y) in all age groups.
