Radiocarbon or C14 dating employs complex systems of measuring the unstable isotopes in once living matter.
Probably the most important factor to consider when using radiocarbon dating is if external factors, whether through artificial contamination, animal disturbance, or human negligence, contributed to any errors in the determinations.
So, an old spear can be tested at the wooden shaft, but not the sharp stone head.
The test will identify about how long ago the wood was cut from a living tree, but cannot tell when it was made into a spear or when the stone head was attached.
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.
The most important archaeological dating method is radiocarbon dating.
It is a technique that can yield absolute dates with accuracy up to approximately 5000 years before present.Carbon dating, or radiocarbon dating, can be helpful in determining the relative age of an object, but has many limitations.The testing for carbon dating relies on many factors and should be used in conjunction with other methods of dating materials.It may conjure up a very odd mental picture, but every living thing on Earth has its own internal clock that's ready to start ticking the moment it dies.And that's what the American physical chemist Willard Libby won the Nobel Prize for when he discovered radiocarbon dating in the late 1940s.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.
