As we know, plants use CO2 (carbon dioxide), H2O (water) and solar rays in order to produce their nutrients.
Some of these carbon dioxide molecules the plant absorbs into its body are molecules formed from radioactive carbon-14.
That is because Carbon-14 is the only radioactive substance found in the bodies of living organisms.
The Earth is constantly being bombarded by cosmic rays from outer space.
These rays strike nitrogen-14, found in high levels in the atmosphere, and transform this into carbon-14, a radioactive substance.
We will deal with carbon dating first and then with the other dating methods.Libby and coworkers and has provided age determinations in archeology, geology, geophysics, and other branches of science.Radiocarbon dating estimates can be obtained on wood, charcoal, marine and freshwater shells, bone and antler, and peat and organic-bearing sediments.Aside from radiocarbon dating, ISO/IEC 17005-accredited Beta Analytic also provides biobased/renewable carbon content testing to manufacturers, product distributors, and researchers worldwide for biobased products, biofuels, waste-derived fuels and their combustion emissions (CO2 gas).The lab also uses Carbon-14 analysis for natural product source testing on materials such as flavors, fragrances, essential oils, cosmetics and supplements to identify petrochemicals.
