Positron emission particle tracking (PEPT) is a powerful, non‐invasive technique that utilises radioactively labelled tracer particles to visualise and quantify the complex internal dynamics of ...

Starting with a set of field experiments piggybacked on a soil flow path tracer experiment at the Rocky Flats site in 1993, we have been investigating the mobilization and transport of particles in ...
