This paper presents radon flux profiles from four regions in Schleswig–Holstein (Northern Germany). Three of these regions are located over deep-rooted tectonic faults or salt diapirs and one is in an area without any tectonic or halokinetic activity, but with steep topography. Contrary to recently published studies on spatial patterns of soil radon gas concentration we measured flux of radon from soil into the atmosphere. All radon devices of each profile were deployed simultaneously to avoid inconsistencies due to strong diurnal variations of radon exhalation. To compare data from different seasons, values had to be normalized. Observed radon flux patterns are apparently related to the mineralogical composition of the Quaternary strata (particularly to the abundance of reddish granite and porphyry), and its grain size (with a flux maximum in well-sorted sand/silt). Minimum radon flux occurs above non-permeable, clay-rich soil layers. Small amounts of water content in the pore space increase radon flux, whereas excessive water content lessens it. Peak flux values, however, are observed over a deep-rooted fault system on the eastern side of Lake Plön, i.e., at the boundary of the Eastholstein Platform and the Eastholstein Trough. Furthermore, high radon flux values are observed in two regions associated with salt diapirism and near-surface halokinetic faults. These regions show frequent local radon flux maxima, which indicate that the uppermost strata above salt diapirs are very inhomogeneous. Deep-rooted increased permeability (effective radon flux depth) or just the boundaries between permeable and impermeable strata appear to concentrate radon flux. In summary, our radon flux profiles are in accordance with the published evidence of low radon concentrations in the “normal” soils of Schleswig–Holstein. However, very high values of radon flux are likely to occur at distinct locations near salt diapirism at depth, boundaries between permeable and impermeable strata, and finally at the tectonically active flanks of the North German Basin.

本文介绍了石勒苏益格-荷尔斯泰因州（德国北部）四个地区的ra通量曲线。这些区域中的三个位于根深蒂固的断层或盐底界之上，一个位于没有任何构造或晕动活动，但地形陡峭的区域。与最近发表的关于土壤ra气浓度空间格局的研究相反，我们测量了从土壤到大气中的flux通量。同时部署每个配置文件的所有simultaneously设备，以免由于strong气呼出量的昼夜变化而导致不一致。为了比较不同季节的数据，必须对值进行归一化。观察到的ra通量模式显然与第四纪地层的矿物学组成有关（特别是与大量带红色的花岗岩和斑岩）有关，以及其粒度（在分类良好的沙/粉砂中通量最大）。最小的flux通量发生在非渗透性的，富含粘土的土壤层之上。孔隙中少量的水会增加ra的通量，而过多的水会减少ra的通量。但是，在波伦湖东侧的深层断层系统（即在Eastholstein平台和Eastholstein槽的边界）观察到峰值通量。此外，在与盐成岩作用和近地表卤代动力学断层有关的两个区域中观察到高ra通量值。这些区域显示出频繁的局部ra通量最大值，这表明盐底物上方的最上层非常不均匀。深层渗透率增加（有效ra通量深度）或仅渗透层和不可渗透层之间的边界似乎使concentrate通量集中。总而言之，我们的ra气通量曲线与石勒苏益格-荷尔斯泰因州“正常”土壤中低concentrations气浓度的公开证据一致。然而，非常高的of通量值可能会发生在深层盐成岩作用附近的不同位置，可渗透层与不可渗透层之间的边界，最后出现在北德盆地的构造活跃侧面。
