A review of present techniques and methodological advances in analyzing Th-234 in aquatic systems

The short-lived thorium isotope Th-234 (half-life 24.1 days) has been used as a tracer for a variety of transport processes in aquatic systems. Its use as a tracer of oceanic export via sinking particles has stimulated a rapidly increasing number of studies that require analyses of Th-234 in both ma...
