摘要：
The exhalation of radon from waters surrounding active fault zones is at present not well understood. In this work, radon concentrations in urban waters around fault zones in Jiaozuo, China were measured using a RAD7 Electronic Radon Detector. The average values of radon concentration in drinking water were 8.90 ± 1.16 and 0.21 ± 0.14 Bq L−1 in the fault and non-fault zones, respectively. The radon concentration decreased with increasing distance from the active faults. The total annual effective doses for adults, children and infants in the fault and non-fault zones through inhalation and ingestion of radon in water were within an acceptable range.
