Particle export and flux through the Mesopelagic in the high-latitude north and South Atlantic
… was tracked using Lagrangian sediment traps and thorium-234 disequilibria. A large pulse of diatom detritus was exported suddenly at the end of the bloom, probably upon impending Si-limitation. The particles were rich in transparent exopolymer particles (TEP, sticky polysaccharides secreted by …

Experimental approaches for the production of thorium-229
… is to produce more of the parent radioisotope, thorium-229 (t1/2=7932 years.) The two methods of production we chose to investigate are 1) the irradiation of a 226Ra target in the High Flux Isotope Reactor (HFIR) at Oak Ridge National Laboratory (ORNL) and 2) the fast neutron irradiation of a …

Der Aktivitätstransport von natürlich bedingtem Thorium in der Inkorporationsüberwachung
… from incorporation of naturally occurring thorium isotopes (Th-232, Th-230, Th-282) is indispensable. If the incorporation rate is known, the dose can be calculated via biokinetic models. But the result is subject to large uncertainties. A comparison of the intake with correlated excretion …
