Radiocarbon dating (usually referred to simply as carbon-14 dating) is a radiometric dating method.

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

Although it may be seen as outdated, many labs still use Libby's half-life in order to stay consistent in publications and calculations within the laboratory.

From the discovery of Carbon-14 to radiocarbon dating of fossils, we can see what an essential role Carbon has played and continues to play in our lives today.

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

In 1940 Martin Kamen and Sam Ruben at the University of California, Berkeley Radiation Laboratory did just that.

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 $$t_$$.They found a form, isotope, of Carbon that contained 8 neutrons and 6 protons.Using this finding Willard Libby and his team at the University of Chicago proposed that Carbon-14 was unstable and underwent a total of 14 disintegrations per minute per gram. From this science, we are able to approximate the date at which the organism were living on Earth.Radiocarbon dating is used in many fields to learn information about the past conditions of organisms and the environments present on Earth.The entire process of Radiocarbon dating depends on the decay of carbon-14.
