Determination of radon concentration in drinking water resources of villages nearby Lalehzar fault and evaluation the annual effective dose
2015
The radon concentration has been measured in 44 drinking water resources, in villages nearby Lalehzar fault in winter 2014. Some samples showed a higher concentration of radon surpassing limit set by EPA. Further, a sample was taken from water distribution networks for these sources of water. Soluble radon concentration was measured by RAD7 device. Range radon concentration was 26.88 and 0.74 BqL−1 respectively. The maximum and minimum annual effective dose for adults was estimated at 52.7 and 2.29 µSvY−1, respectively. Reducing radon from water before use is recommended to improve public health.
