Seasonal Variations in Radon and Thoron Exhalation Rates from Solid Concrete Interior Walls Observed Using In Situ Measurements

Atmosphere
Building materials, such as brick and concrete, are known indoor radon (222Rn) and thoron (220Rn) sources. Most radon and thoron exhalation studies are based on the laboratory testing of pieces and blocks of such materials.

Radon and Thoron in Volcanic, Tectonic, and Hydrothermal Systems: A Critical Synthesis and Reduced Inference Framework

Geosciences
Radon (222Rn) and thoron (220Rn) are widely used to investigate diffuse degassing, fault-zone permeability, hydrothermal circulation, and subsurface unrest, but their signals are not direct proxies for a single process.
