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.

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.

The entire process of Radiocarbon dating depends on the decay of carbon-14.

This process begins when an organism is no longer able to exchange Carbon with their environment.

Although it may be seen as outdated, many labs still use Libby's half-life in order to stay consistent in publications and calculations within the laboratory.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.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.From that point on, scientist have used these techniques to examine fossils, rocks, and ocean currents and determine age and event timing.Throughout the years measurement tools have become more technologically advanced allowing researchers to be more precise and we now use what is known as the Cambridge half-life of 5730 /- 40 years for Carbon-14.In contrast, living material exhibit an activity of 14 d/min.g.Thus, using Equation \(\ref\), \[\ln \dfrac = (1.21 \times 10^) t \nonumber\] Thus, \[t= \dfrac = 2 \times 10^3 \text \nonumber\] From the measurement performed in 1947 the Dead Sea Scrolls were determined to be 2000 years old giving them a date of 53 BC, and confirming their authenticity.Thus, the Turin Shroud was made over a thousand years after the death of Jesus.The technique of radiocarbon dating was developed by Willard Libby and his colleagues at the University of Chicago in 1949. 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.
