Description

A mapping survey of 222Rn and 220Rn concentrations in soil gas was conducted for the first time using a RAD7 portable radon monitor at 67 locations across an area of 1800 km2 in Zhongshan City (ZSC), Guangdong Province. It was found that 222Rn concentrations increased with increasing depth, whereas 220Rn concentrations were almost unchanged at different depths. The sites with high 222Rn values were located mainly in granite outcrops, while those with low values were located in a sedimentary region. The distribution patterns of 220Rn coincide with the patterns of activity concentration of 232Th in soil. (author)
