Comment/Description

Course content:
Radium (223Ra, 224Ra, and 226Ra) and Radon (222Rn) isotopes are commonly used as (i) geochemical clocks to calculate residence times, and (ii) tracers to establish mass balances and calculate volumetric fluxes. Their major advantages are a simple, cost-effective analysis as well as a broad versatility. They have been applied to investigate groundwater-surface water interactions, pore water fluxes across the sediment-water interface, and dynamics of hydrothermal vent systems.
In the scope of this short introductory course, we will review the basics of radiochemistry, explore the utility of the U-Th series radionuclides in geochronology and flux calcuations, and establish an overview about analytical approaches and environmental applications. The course will include a field trip to Spiekeroog Island, where samples will be collected and analyzed later at ICBM in Oldenburg.
A background in (geo)chemistry or radiochemistry is desirable, but not required. However, due to the limited space and time-intensive supervision, this course is limited to 4 participants on a first-come-first-serve basis. Please register via StudIP.
If you have any questions please contact Dr. Hannelore Waska: hannelore.waska@uni-oldenburg.de
