摘要

Radon (222Rn), among all natural radiation sources, is considered the most hazardous to human health. This study evaluated the 222Rn concentration and radiological risk in the surface water and groundwater in Dareta Village. The water samples were randomly collected, and 222Rn was measured using a DURRIDGE-RAD7 analyzer. The mean 222Rn concentration was in the range of 2.64 ± 0.10–12.30 ± 3.20 Bq/l, and the mean of the total annual effective dose was 12.54–82.02 µSv/y. Based on these findings, it can be concluded that the 222Rn concentrations were safe, except for ZGW-01 and ZGW-02. However, it is recommended that water samples be treated before consumption.
