Radiation-based single particle tracking approaches have distinct advantages in investigating opaque particle systems such as fluidized beds. The principles of one of these – positron emission particle tracking (PEPT) – are summarised here, together with recent developments in the use of the technique. Applications in bubbling beds, circulating beds, in heat transfer and in coating are illustrated. PEPT is beginning to be used in validation of computational methods for simulating fluidized beds, such as discrete element methods.
