One million year old groundwater in the Sahara revealed by krypton-81 and chlorine-36
N. C. Sturchio, X. Du, R. Purtschert +15
Measurements of 81Kr/Kr in deep groundwater from the Nubian Aquifer (Egypt) were performed by a new laser-based atom-counting method. 81Kr ages range from \~2x10^5 to ~1x10^6 yr, c…

A New Method of Measuring 81Kr and 85Kr Abundances in Environmental Samples
X. Du, R. Purtschert, K. Bailey +7
We demonstrate a new method for determining the 81Kr/Kr ratio in environmental samples based upon two measurements: the 85Kr/81Kr ratio measured by Atom Trap Trace Analysis (ATTA)…
