Abstract
International Workshop on Tracer Applications of Noble Gas Radionuclides; Argonne, Illinois, 21-22 June 2012 The noble gas radionuclides krypton-81 ( 81Kr; 229,000-year half-life), krypton-85 ( 85Kr; 10.8-year half-life), and argon-39 ( 39Ar; 269-year half-life) have ideal properties for tracing fluid transport in Earth systems. Their principal applications include determination of groundwater residence times ( 81Kr, 85Kr, and 39Ar) and seawater ventilation ages ( 39Ar). In practice, however, few studies have employed noble gas radionuclides because of the large sample sizes required and the complex analytical systems required for measuring their extremely low isotopic abundances (10-16 to 10-11). Most published studies have used low-level radioactive decay counting for 39Ar and 85Kr, but the low activity of 81Kr has necessitated the development of various atom-counting methods over the past 4 decades.
