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.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.Libby and coworkers and has provided age determinations in archeology, geology, geophysics, and other branches of science.Radiocarbon dating estimates can be obtained on wood, charcoal, marine and freshwater shells, bone and antler, and peat and organic-bearing sediments.The currently accepted value for the half-life of will remain; a quarter will remain after 11,460 years; an eighth after 17,190 years; and so on.

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.

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.
