Abstract:
In the present investigation, the groundwater in Zarand region was analyzed to determine radon gas concentration and its relationship with geological structure and physicochemical parameters of the groundwater. Based on the results of experimental measurements for 48 groundwater samples taken from agricultural deep wells using the RAD7 electronic detector, it was shown that 48% of the samples had radon concentrations above 11BqL-1 level. In fact, the measured values for radon gas concentrations ranged between 4.667 ± 2.077 and 31.550 ± 4.912 BqL-1. The results showed that there was a significant relationship between the radon gas concentrations in the groundwater with the distance of wells from the fault, electrical conductivity and PH of water (p < 0.05). However, no relationship between the radon gas concentration and water temperature of the selected samples was observed (p > 0.05).
