Background: Evaluation of the various types of water reveal that groundwater comprises 99% of the earth’s available fresh water. Many factors affect the type and degree of mineralization, as well as the natural radionuclides content in these types of water. The consumption of bottled natural mineral water, which comes from groundwater, among Iranians is gradually increasing. Therefore, the detection of high concentrations of radionuclides, associated with consumption of groundwater, is proposed as a public health problem in several areas. Methods: In this study, the activity concentration of natural radionuclides such as 226Ra, 228Ra, 210Pb, and 40K, annual effective dose for three age groups (<1 year, 7-12 years, and >17 years), and excess lifetime cancer risk due to the ingestion of natural radionuclides present in 70 different commercial bottled mineral waters from most provinces of Iran, were evaluated. Activity concentrations were measured using gamma spectrometry and a high purity germanium detector (HPGe). Results: The results showed that the activity concentrations of natural radionuclides were higher than those reported in the same studies in other countries. Also, the annul effective dose for the three age groups was much higher than the recommended value (0.1 mSvyr-1), as reported by the WHO. The excess lifetime cancer risk for three radionuclides, 226Ra, 228Ra, and 40K, were less than the acceptable value of 10-3 for radiological risk, while the risk for 210Pb was higher than the recommended value. Conclusion: According to the results of this study, the frequent use of bottled waters produced in different provinces of Iran possess health hazards to consumers.

Abstract With gamma spectrometric method 23 samples of mineral and thermal waters of Bosnia and Herzegovina were analyzed. Activity concentrations of the investigated radionuclides were in the range 12–346 mBq·L−1 for 40K, 1.1–791 mBq·L−1 for 226Ra, 0.2–221 mBq·L−1 for 228Ra, 13–367 mBq·L−1 for 238U, and 0.6–17 mBq·L−1 for 235U. For all investigated radionuclides annual effective dose was estimated. The estimated total annual committed effective dose received by population as a result of ingestion of water was in the range 0.11–2.51 μSv·y−1 for thermal water and in the range 0.11–38.8 μSv·y−1 for mineral water. Measurement of activity concentrations of natural radionuclides in the examined samples was carried out with a gamma-spectrometer with high-purity germanium (HPGe) detector, having a relative efficiency of 70%.

This paper has explained the contamination of natural radionuclides in various water testers using gamma ray measurement which is very significant as part of health scrutiny programs to progress the ecological knowledge. Natural radioactivity was determined in five groups of water samples (rain, mine, tap, drinking and mineral) from different places at Johor, Malaysia by means of gamma-ray spectrometry tool. The annual cumulative effective doses were estimated 6.05 mSv /yr for rain, 9.49 mSv/ yr for mine, 6.39 mSv /yr for tap, 5.67 mSv /yr for drinking, and 6.01 mSv/yr for mineral water. Among the five samples, mine water gave the highest value in annual effective dose measurement. The measured data are compared with the reported value. The activity concentrations of five water samples provided that bottled drinking water was the lowest than other water samples. This research is useful to provide some information to the public about the amount of radionuclide content uranium, thorium and potassium that present in water.
