Radiocarbon dating error margin

When the stocks of Oxalic Acid I were almost fully consumed, another standard was made from a crop of 1977 French beet molasses.

The new standard, Oxalic Acid II, was proven to have only a slight difference with Oxalic Acid I in terms of radiocarbon content.

When they die, they stop exchanging carbon with the biosphere and their carbon 14 content then starts to decrease at a rate determined by the law of radioactive decay.

Radiocarbon dating is essentially a method designed to measure residual radioactivity.

No other scientific method has managed to revolutionize man’s understanding not only of his present but also of events that already happened thousands of years ago.

Archaeology and other human sciences use radiocarbon dating to prove or disprove theories.

Over the years, other secondary radiocarbon standards have been made.

Radiocarbon activity of materials in the background is also determined to remove its contribution from results obtained during a sample analysis.

American physical chemist Willard Libby led a team of scientists in the post World War II era to develop a method that measures radiocarbon activity.

He is credited to be the first scientist to suggest that the unstable carbon isotope called radiocarbon or carbon 14 might exist in living matter. Libby and his team of scientists were able to publish a paper summarizing the first detection of radiocarbon in an organic sample. Libby who first measured radiocarbon’s rate of decay and established 5568 years ± 30 years as the half-life. Libby was awarded the Nobel Prize in Chemistry in recognition of his efforts to develop radiocarbon dating.1.

By knowing how much carbon 14 is left in a sample, the age of the organism when it died can be known.

It must be noted though that radiocarbon dating results indicate when the organism was alive but not when a material from that organism was used.

The radiocarbon age of a certain sample of unknown age can be determined by measuring its carbon 14 content and comparing the result to the carbon 14 activity in modern and background samples.
