低水平航空辐射测量提供了土壤上半米中伽马发射元素（包括钾（K），钍（Th）和铀（U））浓度的数据。在风化没有渗透到这个深度之外的地方，如在覆盖英格兰和威尔士大部分地区的年轻土壤中，信号可能与土壤的粘土含量及其母体物质有关。在这些情况下，放射性测量可能是有价值的土壤数字制图。
A low‐level airborne radiometric survey provides data on the concentrations of gammaemitting elements including potassium (K), thorium (Th) and uranium (U) in the upper half metre of the soil. Where weathering has not penetrated much beyond this depth, as in the young soils that cover much of England and Wales, the signal is likely to be related to the soil's clay content and its parent material. In these situations radiometric survey could be valuable for mapping soil digitally.
