Radioactivity is ubiquitous in the natural environment as a result of i) cosmic radiation from space and secondary radiation from the interaction of cosmic rays with atoms in the atmosphere, ii) terrestrial sources from mineral grains in soils and rocks, particularly Potassium (K-40), Uranium (U-238) and Thorium (Th-232), and their decay products, and iii) Radon gas (Rn-222). The use of nuclear techniques enables the measurement of natural radioactivity in air, soils and water even at trace levels, making it a particularly appealing tool for characterizing time-varying environmental phenomena. This session welcomes contributions addressing the measurement and exploitation of environmental radioactivity in all areas of geosciences, including, but not limited to:

- volcanic monitoring and surveillance;
- identification of faults and tectonic structures;
- earthquakes;
- groundwater contamination;
- coastal and marine monitoring;
- atmospheric tracing, including of greenhouse gases and pollutants;
- air ionisation and atmospheric electricity;
- cosmic rays;
- public health including the EU BSS directive.

Contributions on novel methods and instrumentation for environmental radioactivity monitoring are particularly encouraged, including payloads for airborne measurements and small satellites.
