Before Radiocarbon dating was able to be discovered, someone had to find the existence of the C isotope.

In 1960, Libby was awarded the Nobel Prize in chemistry for this work.

He demonstrated the accuracy of radiocarbon dating by accurately estimating the age of wood from a series of samples for which the age was known, including an ancient Egyptian royal barge dating from 1850 BCE.

Using this hypothesis, the initial half-life he determined was 5568 give or take 30 years.

The accuracy of this proposal was proven by dating a piece of wood from an Ancient Egyptian barge, of whose age was already known.

Once an organism is decoupled from these cycles (i.e., death), then the carbon-14 decays until essentially gone.

The half-life of a radioactive isotope (usually denoted by $$t_$$) is a more familiar concept than $$k$$ for radioactivity, so although Equation $$\ref$$ is expressed in terms of $$k$$, it is more usual to quote the value of $$t_$$.

This discovery is in contrast to the carbon dating results for the Turin Shroud that was supposed to have wrapped Jesus’ body.

Carbon dating has shown that the cloth was made between 12 AD.

From this science, we are able to approximate the date at which the organism were living on Earth.
