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.
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.
Interested in radio physics in general, the lab built a 60-foot (18 m)-diameter radio telescope on Point Loma, and in 1964, NEL began construction of the La Posta Astro-Geophysical Observatory on a 3,900-foot (1,200 m) site in the Laguna Mountains, 65 miles (105 km) east of San Diego.

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]
