Abstract

Argon-39 can be used as a tracer for age-dating glaciers, oceans, and more recently, groundwater. With a half-life of 269 years, ³⁹Ar fills an intermediate age range gap (50–1,000 years) not currently covered by other common groundwater tracers. Therefore, adding this tracer to the data suite for groundwater studies provides an important tool for improving our understanding of groundwater systems. Lastly, we present the methods employed for arriving at an age-date for a given sample of argon degassed from groundwater.

The age of Lathrop Wells volcanic center: An {sup 40}Ar/{sup 39}Ar dating investigation

Journal Article Heizler, M T ; Peters, L ; Appelt, R ; ... - Journal of Geophysical Research

The {sup 40}Ar/{sup 39}Ar age spectrum analyses of basalt whole rock and partially degassed sanidine xenocrysts for the Lathrop Wells volcanic center, Nevada, yield eruption ages of 77.3{plus_minus}6.0 and 76.6{plus_minus}4.9; ka (2{sigma}) for the Ql{sub 1} and Ql{sub 2} flows, respectively. Basaltic samples were analyzed in four to six replicate runs and yield normally distributed plateau ages. Miocene ash flow tuff xenoliths were collected from the basaltic units with the majority of samples coming from the Ql{sub 2}. The sanidines from the Ql{sub 2} xenoliths yielded apparent plateau ages (n=10) ranging from 69{plus_minus}17 to 309{plus_minus}11; ka with a strong clustermore »« less

Age dating of rocks with [sup 40]Ar/[sup 39]Ar at the Ford Nuclear Reactor

Conference Burn, R R ; Simpson, P A ; Cook, G M - Transactions of the American Nuclear Society; (United States)

The discovery of radioactivity by Becquerel in 1896 laid the foundation for direct measurement of the physical age of rocks and led to the development of the field of geochronology by isotopic dating. The element potassium is utilized in age dating. Potassium is the eighth most abundant element; [approximately]1% of the earth's crust is potassium. Natural potassium is composed of three isotopes: [sup 39]K, which is stable and 93.3% abundant; [sup 41]K, which is stable and 6.7% abundant; and [sup 40]K, which has a trace abundance of 0.012% and is radioactive with a half-life of 1.28 billion years.

39Ar/Ar measurements using ultra-low background proportional counters

Journal Article Hall, Jeter C. ; Aalseth, Craig E. ; Bonicalzi, Ricco ; ... - Applied Radiation and Isotopes

Age dating groundwater and seawater using 39Ar/Ar ratios is an important tool to understand water mass flow rates and mean residence time. For modern or contemporary argon, the 39Ar activity is 1.8 mBq per liter of argon. Radiation measurements at these activity levels require ultra low-background detectors. Low-background proportional counters have been developed at Pacific Northwest National Laboratory. These detectors use traditional mixtures of argon and methane as counting gas, and the residual 39Ar from commercial argon has become a predominant source of background activity in these detectors. We demonstrated sensitivity to 39Ar by using geological or ancient argon frommore »« less

Simultaneous measurement of tritium and radiocarbon by ultra-low-background proportional counting

Journal Article Mace, Emily ; Aalseth, Craig ; Alexander, Tom ; ... - Applied Radiation and Isotopes

Use of ultra-low-background capabilities at Pacific Northwest National Laboratory provide enhanced sensitivity for measurement of low-activity sources of tritium and radiocarbon using proportional counters. Tritium levels are nearly back to pre-nuclear test backgrounds (~2-8 TU in rainwater), which can complicate their dual measurement with radiocarbon due to overlap in the beta decay spectra. In this paper, we present results of single-isotope proportional counter measurements used to analyze a dual-isotope methane sample synthesized from ~120 mg of H₂O and present sensitivity results.
