Background and Objectives: Entrance of high concentration of Radon gas through drinking water or inhaling Radon gas released into the air from water can cause lung cancer. This study aimed to measure Radon gas dissolved in groundwater and to determine the annual effective absorbed dose of Radon gas in Zarand city.
Materials and Methods: This descriptive study was done on 48 randomly selected resources of agricultural water in Zarand in 2016. The annual absorbed dose of Radon gas by adults and children was estimated through the measurement of the concentration of dissolved Radon gas using portable RAD7electronic detector. Data was analyzed by one sample t-test.
Results: The minimum and maximum amounts of Radon gas in the samples were 4.667±2.077 and 31.550±4.912 BqL-1, respectively. Therefore, the annual absorbed doses of Radon gas by adults and children drinking agricultural water were between 45.736±20.354 and 309.190±48.137 µSv/year and 62.770±27.935 and 424.347±66.066 µSv/year, respectively. Accurate investigation of data by one sample t- test showed that the annual absorbed doses by adults and children were significantly higher than the standard amount (p=.017 for adults and p>.001 for children).
Conclusion: Radon gas concentration dissolved in the water of Zarand region was high. The natural radiation can be reduced by not using water at the well, aeration of water in the reservoir, and informing the residents about  the amount of background Radon gas concentration dissolved in agricultural wells.
