Understand how decay and half life work to enable radiometric dating.By comparing this with modern levels of activity (1890 wood corrected for decay to 1950 AD) and using the measured half-life it becomes possible to calculate a date for the death of the sample.As 14C decays it emits a weak beta particle (b ), or electron, which possesses an average energy of 160ke V.Included below is an impressive list of some of the types of carbonaceous samples that have been commonly radiocarbon dated in the years since the inception of the method: The historical perspective on the development of radiocarbon dating is well outlined in Taylor's (1987) book "Radiocarbon Dating: An archaeological perspective".

Libby and his team intially tested the radiocarbon method on samples from prehistoric Egypt.

Radiocarbon dating has been one of the most significant discoveries in 20th century science.
