Thorium-234 is produced in the oceans via the decay of its long-lived and highly soluble "parent", 238U. The activities of these two radionculides reach secular equilibrium (i.e. are identical) at relatively shallow depths of 100-200m. Since 234Th chemistry dictates that it is highly particle-reactive, and hence sticks to all particle surfaces ...Web
