In the town of Kahramanmaraş, Turkey, a study was conducted to measure radon levels in bottled drinking water. Radon is a naturally occurring radioactive gas that can be harmful if ingested or inhaled. The study focused on eight different brands of bottled water, which were purchased from local markets. These brands represent a significant portion of the bottled water consumed in the region.

        Researchers used a Durridge Rad7 detector to measure radon activity in 32 water samples of varying volumes. The average radon activity concentration found was 21. 21 ± 1. 50 mBq/L, with levels ranging from 13. 50 ± 1. 30 to 31. 70 ± 2. 20 mBq/L. These findings are important because they help us understand the potential health risks associated with consuming bottled water containing radon.

        The study also calculated the total annual effective dose equivalent (AEDE) for different age groups. For infants (1-2 years), children (2-12 years), and adults (>17 years), the estimated mean AEDE values were 7. 43E-05, 4. 39E-05, and 5. 43E-05 mSv y^-1, respectively. These values indicate the amount of radiation exposure from ingesting and inhaling radon in bottled water over a year.

        For adults, the excess lifetime cancer risk (ELCR) was calculated to be 2. 40E-07. This means that the likelihood of developing cancer from radon exposure through bottled water is very low. However, it is still important to consider this risk, especially for those who consume large amounts of bottled water.

        Radon in water is a concern because it can seep into groundwater from the surrounding soil and rock. This is a natural process, but it can be exacerbated by human activities such as mining and drilling. Understanding the levels of radon in bottled water is crucial for public health, as it allows us to make informed decisions about our water consumption.

        The study highlights the importance of monitoring radon levels in bottled water. While the risks are low, they are not zero. It is essential to continue researching and regulating radon levels to ensure the safety of our drinking water. This is especially true for vulnerable populations, such as infants and children, who may be more susceptible to the effects of radon exposure.
