In contrast to relative dating techniques whereby artifacts were simply designated as "older" or "younger" than other cultural remains based on the presence of fossils or stratigraphic position, 14C dating provided an easy and increasingly accessible way for archaeologists to construct chronologies of human behavior and examine temporal changes through time at a finer scale than what had previously been possible.

The application of Accelerator Mass Spectrometry (AMS) for radiocarbon dating in the late 1970s was also a major achievement.

We will deal with carbon dating first and then with the other dating methods.

Carbon has unique properties that are essential for life on Earth.

This tendency to decay, called radioactivity, is what gives radiocarbon the name radiocarbon.

The atmosphere contains many stable carbon atoms and relatively few radiocarbon atoms.

The Shroud of Turin , which many people believe was used to wrap Christ's body, bears detailed front and back images of a man who appears to have suffered whipping and crucifixion.Compared to conventional radiocarbon techniques such as Libby's solid carbon counting, the gas counting method popular in the mid-1950s, or liquid scintillation (LS) counting, AMS permitted the dating of much smaller sized samples with even greater precision.Regardless of the particular 14C technique used, the value of this tool for archaeology has clearly been appreciated.It was first displayed at Lirey in France in the 1350s and subsequently passed into the hands of the Dukes of Savoy.After many journeys the shroud was finally brought to Turin in 1578 where, in 1694, it was placed in the royal chapel of Turin Cathedral in a specially designed shrine.The following article is primarily based on a discussion of radiocarbon dating found in The Biblical Chronologist Volume 5, Number 1. Radiocarbon dating is based on a few relatively simple principles. The vast majority of these are C (pronounced "c twelve"), the stable isotope of carbon.
