Radiometric dating assumptions

The World Ocean Circulation Experiment from 1990 to 2002 obtained radiocarbon measurements from dissolved inorganic carbon.

Radiocarbon dating rests heavily on this assumption such that other sources of carbon 14 had, at first, not been considered nor accounted for.The change in global radiocarbon levels brought about by human activities necessitated the use of a reference standard for carbon 14 dating. National Bureau of Standards had been adopted as standard for radiocarbon dating.Radiocarbon dating needed an organic material that was not contaminated with carbon 14 from fossil fuel burning or nuclear weapons testing. Its radiocarbon content was theoretically the same as a wood sample grown in AD 1950, the zero point of the radiocarbon timescale used in quoting carbon dating results.Radiocarbon Dating Cost To provide you with the best possible user experience, this website uses cookies.If you continue to browse this site, you are agreeing to our use of cookies.

Nowadays, radiocarbon scientists had to perform calibration not only to convert their radiocarbon year results into calendar year but also to take into account the various factors that have major effects on the global levels of carbon 14, one of which is nuclear weapons testing.
