  2. Radiocarbon dating - Wikipedia

    en.wikipedia.org/wiki/Radiocarbon_dating

    C quickly combines with the oxygen (O) in the atmosphere to form first carbon monoxide (CO), [14] and ultimately carbon dioxide (CO 2). [15] 14 C + O 2 → 14 CO + O 14 CO + OH → 14 CO 2 + H. Carbon dioxide produced in this way diffuses in the atmosphere, is dissolved in the ocean, and is taken up by plants via photosynthesis.

  3. Carbon-14 - Wikipedia

    en.wikipedia.org/wiki/Carbon-14

    Carbon-14, C-14, 14 C or radiocarbon, is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons. Its presence in organic matter is the basis of the radiocarbon dating method pioneered by Willard Libby and colleagues (1949) to date archaeological, geological and hydrogeological samples.

  6. Radiocarbon dating samples - Wikipedia

    en.wikipedia.org/wiki/Radiocarbon_dating_samples

    Wood contains cellulose, lignin, and other compounds; of these, cellulose is the least likely to have exchanged carbon with the sample's environment, so it is common to reduce a wood sample to just the cellulose component before testing. However, this can reduce the volume of the sample down to 20% of the original size, so testing of the whole ...

    Since it was produced after the start of nuclear weapon testing it incorporates carbon-14 produced by neutrons in the atmosphere, so the activity is higher than the desired standard, and this oxalic acid, having been produce from beets, had a δ 13 C value of -19.3‰. [9]
