Cambridge carbon dating

We wanted to use science to test the accepted historical dates of several Old Kingdom monuments.One radioactive, or unstable, carbon isotope is C14, which decays over time and therefore provides scientists with a kind of clock for measuring the age of organic material.

So, every living thing is constantly exchanging carbon-14 with its environment as long as it lives. The carbon in its body will remain until it decomposes or fossilizes.

The numbers of C14 atoms and non-radioactive carbon atoms remain approximately the same over time during the organism’s life.

As soon as a plant or animal dies, the carbon uptake stops.

Libby calculated the half-life of carbon-14 as 5568, a figure now known as the Libby half-life.

Following a conference at the University of Cambridge in 1962, a more accurate figure of 5730 years was agreed upon and this figure is now known as the Cambridge half-life.

This is known as the Cambridge half-life. To convert a "Libby" age to an age using the Cambridge half-life, one must multiply by 1.03. The major developments in the radiocarbon method up to the present day involve improvements in measurement techniques and research into the dating of different materials.

Many people assume that rocks are dated at “millions of years” based on radiocarbon carbon-14 dating. But that’s not the case.

All living things are built of carbon atoms. There are various isotopes, or species, of carbon atoms with the same atomic number but different mass. One radioactive, or unstable, carbon isotope is C14, which decays over time and therefore provides scientists with a kind of clock for measuring the age of organic material.

Archaeology is the study of the human past, in all its social and cultural diversity. At Cambridge it is an outstandingly broad and exciting subject, equally rewarding for those who feel at home in the sciences, the humanities, or both.

Carbon Dating - Learn about carbon dating and how it is used to estimate the age of carbon-bearing materials between 58,000 to 62,000 years.

Radiocarbon dating is the principal method for determining the age of carbon-bearing materials from the present to about 50,000 years ago.
