Radiocarbon dating (usually referred to simply as carbon-14 dating) is a radiometric dating method.It uses the naturally occurring radioisotope carbon-14 (14C) to estimate the age of carbon-bearing materials up to about 58,000 to 62,000 years old. Carbon-14 has a relatively short half-life of 5,730 years, meaning that the fraction of carbon-14 in a sample is halved over the course of 5,730 years due to radioactive decay to nitrogen-14.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.

Carbon dating has given archeologists a more accurate method by which they can determine the age of ancient artifacts.

Carbon-14 is constantly be generated in the atmosphere and cycled through the carbon and nitrogen cycles.

Emilio Segrè asserted in his autobiography that Enrico Fermi suggested the concept to Libby at a seminar in Chicago that year.

Libby estimated that the steady-state radioactivity concentration of exchangeable carbon-14 would be about 14 disintegrations per minute (dpm) per gram.

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.

Although it may be seen as outdated, many labs still use Libby's half-life in order to stay consistent in publications and calculations within the laboratory.
