【摘要】 空气氡主要来源于岩石和土壤 ,受地质背景控制。本文讨论了近地表空气中氡运移理论方程 ,并给出了室内模型试验和青岛、江西两地实测结果与理论预测的误差 ,进而讨论了扩散系数、对流系数及氡析出率等参数的选择问题。更多还原

【Abstract】 Radon in air comes mainly from rocks and soils is controlled by the geological background.The equation of radon transport in air near earth is presented in this paper,as well as the results of model experiments and measurements in Qingdao and Linchuan.Furthermore,it is discussed how to choose the parameters of diffusion,convection and exhalation.更多还原
