Description
In order to study the relationship between the radon concentration and the depth of shallow soil in Beijing area, field survey of soil using RAD7 electronic radon monitor has been performed along with collection of soil samples. The survey of 9 sample sites was carried out in Tongzhou Distinct, Fengtai District, Mentougou district and Yanqing County, respectively. The soil radon concentrations at 20 cm, 40 cm, 60 cm, 80 cm and 100 cm depth were measured and the radium specific activities of the collected samples were analyzed with indoor HPGe γ spectrometer. The results showed that the concentration of soil radon increased with the increase of soil depth in shallow soil, and there was a positive correlation between soil radon concentration and specific activity of radium in soil samples. Compared with the radon concentration in the sandy soil, the concentration of radon in the clayey soil is higher. (authors)
