Abstract The Radon (Rn) deficit technique is a rapid, low-cost, and non-invasive method to
identify and quantify light non-aqueous phase liquids (LNAPL) in the soil. LNAPL saturation …

222Radon (Rn) was proposed in the late 1990s as a naturally occurring tracer for light non-
aqueous phase liquids (LNAPLs) in the subsurface, due to its preferential partitioning …

Featured Application Radon deficit reveals the presence of residual NAPL (Non-Aqueous
Phase Liquid) contamination in soil and groundwater, giving a good picture of their vertical …

The performance of the radon (222 Rn)-deficit technique has been evaluated at a site in
which a complex DNAPL mixture (mostly hexachlorocyclohexanes and chlorobenzenes) …

The application of the 222 Radon (Rn) deficit technique using subsurface soil gas probes for
the identification and quantification of light non-aqueous phase liquids (LNAPL) has …

Temporal dynamic as well as spatial variability of environmental radon are controlled by
factors such as meteorology, lithology, soil properties, hydrogeology, tectonics, and …

The radon-deficit technique is a powerful tool to detect and delineate sub-surface
accumulations of organic contaminants. Field measurements of 222 Rn in soil air, however …

A rapid method for local-scale radon risk assessment using in situ radon soil-gas
measurements and a national-scale soil permeability data set have been evaluated. We test …

The information obtained in the initial characterization of contaminated sites is essential for
their correct environmental assessment, management and eventual remediation. In the case …

Uncontrolled landfill sites are one of the main sources of underground and surface water
contamination. The absence of monitoring leads to the leakage of leachates into the …
