This process of decay occurs at a regular rate and can be measured.
By comparing the amount of carbon 14 remaining in a sample with a modern standard, we can determine when the organism died, as for example, when a shellfish was collected or a tree cut down.
This creates an error in the "raw" age of about 2 percent.
Since nearly all applications where the precise age is needed require calibration, this difference is removed in the calibration process].
The Radiocarbon Revolution Since its development by Willard Libby in the 1940s, radiocarbon (14C) dating has become one of the most essential tools in archaeology.
Radiocarbon dating was the first chronometric technique widely available to archaeologists and was especially useful because it allowed researchers to directly date the panoply of organic remains often found in archaeological sites including artifacts made from bone, shell, wood, and other carbon based materials.
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.
The formula used for this calculation is: Radiocarbon age (years BP) = -C in 1950 AD (pre-bomb) material.
For practical reasons, which are discussed later, the value of "modern" is defined by reference to two primary standards of known radiocarbon content.
However, there are a number of other factors that can affect the amount of carbon present in a sample and how that information is interpreted by archaeologists.
Thus a great deal of care is taken in securing and processing samples and multiple samples are often required if we want to be confident about assigning a date to a site, feature, or artifact (read more about the radiocarbon dating technique at:
