This multi-year study investigates if flow/topography interactions are reflected in distributional patterns of the natural short-lived (half-life: 24.1 d) particulate-matter tracer 234Th relative to its conservative (non-particle-reactive) and very long-lived parent nuclide 238U. The sampling sites ...
228Th has a half life of 1.91 years and is produced from 228Ra with 228Ac as a very shortlived intermediate daughter. Sources of 228Th to coastal waters are rivers, in situ production and lateral transport of offshore water. 210Pb is produced from the decay of its effective parent, 226...

The activity of the short-lived 234Th (half-life = 24 days) is found to be in marked radioactive disequilibrium with respect to the concentration of its parent. 238U in the top hundred meters of the sea water column; values above and below secular equilibrium exist. The mechanisms ...
The short-lived radionuclides 7Be (half-life = 53.3 days) and 234Th (half-life = 24.1 days) serve as tracers of particle dynamics on short-term (seasonal) time scales, while the longer lived 210Pb (half-life = 22.3 y) traces the fate of particles on decadal time scales. In Jamaica ...
