Soil radon depth dependence

Abstract

The knowledge of the soil radon levels is important for the planning and construction of new buildings in order to estimate the radon risk and to classify the ground for construction purposes. The purpose of this investigation was to study in situ the radon levels at various depths 0-2 m in terrain where the geology is comparatively uniform. The data from the measurements was fitted to simple functions in order to facilitate future extrapolations of radon levels from various depths to 1 m at measurements anywhere. The plastic film Kodak LR 115 was used as the detector of the radon levels at four different depths in the interval 0-2 m. The measurements were made along a 2200 m long profile at 16 different points. © 2001 Elsevier Science Ltd. All rights reserved.
