Fractured and karstified aquifers are often vulnerable to pollution by nitrate or other anthropogenic compounds. Therefore, a better understanding of the flow and transport processes in these aquifers is imperative for effective drinking water management. In this study, we used the analysis of tritium and tritiogenic helium-3 concentrations to estimate the residence and exposure time of nitrate transported in a fractured groundwater system of the Upper Muschelkalk in southwest Germany.
late s onwards. Between and , tritium dating the ages of groundwaters that are less than about. 60 years element, in this case helium (3He).
Helium consists of two stable isotopes: 3 He and 4 He. Although chemically identical their nuclei contain 2 protons each they each have different numbers of neutrons, and hence atomic mass. Thus it is present only at a level of only about 2 nano-moles per kg of seawater. That is, there is only one atom of 3 He for every , atoms of 4 He in air.
Thus 3 He is a million times less abundant than it’s more prolific cousin. Aside from He dissolved from the atmosphere, there are two other sources of non-atmospheric He in the ocean.
Identify a drawback of using radiometric dating to determine the age of a fossil
Tritium 3 H, half-life of Tritium input to ground water has occurred in a series of spikes following periods of atmospheric testing of nuclear devices that began in and reached a maximum in Concentrations of 3 H in precipitation have decreased since the mids bomb peak, except for some small increases from French and Chinese tests in the late s. Radioactive decay of 3 H produces the noble gas helium-3 3 He.
Tritium measurements alone can be used to locate the depth of the mids bomb peak, but, because of radioactive decay, many samples may need to be collected and analyzed today to locate its position. In systems younger than the mids, the bomb peak will not be present due to radioactive decay.
