The spatial variations of soil gas in the northern edge of West Qinling Fault were investigated based on the field measurement of radon concentration. Radon concentrations highlighted a decreasing gradient from the middle segment to NW and SE along the fault and the fault zone was divided into three segments. We observed that the measured radon data showed a moderate positive correlation with relative fault activity. The hazard segment area was marked according to the relationship between the spatial concentration anomaly values of soil-gas radon and the seismotectonic background.

    Radon and its progenies have been ranked second of being responsible for lung cancer in humans. Hong Kong has four major groups of uranium-rich plutonic and volcanic rocks and is suffering from radon emanated therefrom. However, there is a lack of radon potential maps in Hong Kong to resolve the...
