Knowing the concentration of 226Ra in soil and of 222Rn in soil gas is important for the analysis of indoor radon data and the prediction of radon-prone areas. Except for soil Rn in Ardenne, the data concerning these two radionuclides in Belgian soils are very scarce. In the context of Master theses and international courses, students made 92 measurements of 226Ra in soil samples, 105 of 222Rn in soil gas, and 74 of soil permeability, a significant addition to the existing similar data. The data are analysed in relation with soil texture, geological units and indoor radon risk. There is no clear correlation between radium in soil and indoor radon risk, the most important factor of risk being soil permeability.
了解土壤中镭 - 226的浓度以及土壤气体中氡 - 222的浓度对于分析室内氡数据和预测氡易发区域很重要。除了阿登地区的土壤氡外，比利时土壤中这两种放射性核素的数据非常稀少。在硕士论文和国际课程的背景下，学生们对土壤样品中的镭 - 226进行了92次测量，对土壤气体中的氡 - 222进行了105次测量，对土壤渗透率进行了74次测量，这是对现有类似数据的显著补充。这些数据与土壤质地、地质单元和室内氡风险相关进行了分析。土壤中的镭与室内氡风险之间没有明显的相关性，最重要的风险因素是土壤渗透率。
