This study describes approaches to create surface maps of radon in groundwater based on
measurements of radon (
222
Rn) in drilled bedrock wells at unevenly distributed sites and uranium
bedrock m...
Tracing and quantifying groundwater inflow into lakes using a simple method for radon-222 analysis

Due to its high activities in groundwater, the radionuclide 222Rn is a sensitive natural tracer to detect and quantify groundwater inflow into lakes, provided the comparatively low activities in the l...
Sensitivity of Global Modeling Initiative chemistry and transport model simulations of radon-222 and lead-210 to input meteorological data
