| 摘 要： | 对北京平原区北西向和北东向两条氡浓度剖面进行了测量，发现北部地区氡背景值要大于南部，东向西方向氡浓度变化起伏频繁。分析其原因主要是受到土壤母质、地层以及断裂的影响，发现断裂是影响北京平原区氡浓度高值的主要因素。

| Abstract: | In order to understand the distribution characteristics of soil radon and its influence factors, the investigation of radon characteristics on the two NW-direction and NE-direction profiles are finished in Beijing plain area. The result indicates that the background radon concentration in the north of the area is much higher than that in the south, and the radon concentration varies obviously from east to west. The soil’s parent material, stratum and fault are the major influence factors that cause the above characteristics. Further more, the fault is the major factor on impacting the radon concentration in Beijing plain area. |
