The key to their application as tracers is that, despite very low solubility in water, they are measurable at very low concentrations owing to their high electron affinity, which results in very sensitive responses in electron capture detectors attached to gas chromatographs. Busenberg, Eurybiades, Plummer, L. Your message to the editors. The ages of the young-water fractions in the Upper Floridan aquifer were mapped throughout the Valdosta area. The number of atoms counted in a given time is directly proportional to the abundance of this isotope in the sample. A record of 36 Cl deposition should therefore be much closer to a direct record of variations in cosmogenic production.
The "art" of 36 Cl analysis was maintained through long-term funding of the PRIME Lab accelerator mass spectrometry NSF facility at Purdue University and at my own laboratory, overcoming the inevitable start-up problems that stall the acquisition of real results.

The total 4 He concentration measured in a groundwater sample can be written as: It appears that you are currently using Ad Blocking software. The departure of Thompson derailed the progress of the research. Drinkard, and P. When asked why she was so concerned about this particular aspect of the proposed investigations, she replied that it was considered the single most critical component of the entire range of research at the site, since the widespread presence of bomb 36 Cl would show that unsaturated fluxes were much greater than anticipated. Tracer Serendipitous.
