Radiocarbon Dating Groundwater The application of radiocarbon dating to groundwater analysis can offer a technique to predict the over-pumping of the aquifer before it becomes contaminated or overexploited.
Tracer-Free AMS Dating Lab Beta Analytic does not accept pharmaceutical samples with "tracer Carbon-14" or any other material containing artificial Carbon-14 to eliminate the risk of cross-contamination.
Radiocarbon activity of materials in the background is also determined to remove its contribution from results obtained during a sample analysis.The method does not count beta particles but the number of carbon atoms present in the sample and the proportion of the isotopes. Samples that have been radiocarbon dated since the inception of the method include charcoal, wood, twigs, seeds, bones, shells, leather, peat, lake mud, soil, hair, pottery, pollen, wall paintings, corals, blood residues, fabrics, paper or parchment, resins, and water, among others.Physical and chemical pretreatments are done on these materials to remove possible contaminants before they are analyzed for their radiocarbon content.Over the years, carbon 14 dating has also found applications in geology, hydrology, geophysics, atmospheric science, oceanography, paleoclimatology and even biomedicine.Radiocarbon, or carbon 14, is an isotope of the element carbon that is unstable and weakly radioactive. Carbon 14 is continually being formed in the upper atmosphere by the effect of cosmic ray neutrons on nitrogen 14 atoms.
