The C14 method has been and continues to be applied and used in many, many different fields including hydrology, atmospheric science, oceanography, geology, palaeoclimatology, archaeology and biomedicine.All plants and animals on Earth are made principally of carbon.The job of a radiocarbon laboratory is to measure the remaining amounts of radiocarbon in a carbon sample.This is very difficult and requires a lot of careful work to produce reliable dates.The relative dating method worked very well, but only in sites which were had a connection to the relative scale. When radiocarbon dating was developed, it revolutionised archaeology, because it enabled them to more confidently date the past, and to build a more accurate picture of the human past.The archaeologist Colin Renfrew (1973) called it the development of this dating method 'the radiocarbon revolution' in describing its great impact upon the human sciences.The half-life refers to the amount of time it takes for half the radiocarbon in a sample of bone or shell or any carbon sample to disappear.

Below is a list of the different kinds of materials which can be dated: Libby tested the new radiocarbon method on carbon samples from prehistoric Egypt whose age was known.

Welcome to the K12 section of the Radiocarbon WEBinfo site.

The aim here is to provide clear, understandable information relating to radiocarbon dating for the benefit of K12 students, as well as lay people who are not requiring detailed information about the method of radiocarbon dating itself.

The radiocarbon method was developed by a team of scientists led by the late Professor Willard F.

Libby of the University of Chicago after the end of World War 2.
