| Abstract: |
| 137Cs contents in farmland soil samples around tails pond of uranium mine were measured and analyzed by High Purity Germanium (HPGe) γ Spectrometer to investigate distribution characteristics of radionuclide 137Cs. The results show that content of 137Cs is highest in marginal area of farmland, while is lowest in central area of farmland. 137Cs mainly distributes in surface soil, and content of 137Cs drops within range of 1 m. Soils in study area affect adsorption of 137Cs, and content of 137Cs is unstable in vertical direction, due to particle size and pH value of soil, local precipitation, and horizontal distance to uranium tailings pond. |
