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.

Carbon-14 dating is a way of determining the age of certain archeological artifacts of a biological origin up to about 50,000 years old.

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

Familiar to us as the black substance in charred wood, as diamonds, and the graphite in “lead” pencils, carbon comes in several forms, or isotopes.

How do scientists know how old an object or human remains are?

What methods do they use and how do these methods work?

Before we get into the details of how radiometric dating methods are used, we need to review some preliminary concepts from chemistry.

Recall that atoms are the basic building blocks of matter.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.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.C and other radioisotopes and techniques used in archaeological, geophysical, oceanographic, and related dating. We also publish conference proceedings and monographs on topics related to our fields of interest. 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.With our focus on one particular form of radiometric dating—carbon dating—we will see that carbon dating strongly supports a young earth.
