Radiocarbon (carbon) is a very unstable element that quickly changes into nitrogen. Half the original quantity of carbon will decay back to the stable element nitrogen after only 5, years. (This 5, year period is called the half-life of radiocarbon, figure 5). 6 At this decay rate, hardly Author: Dr. Andrew A. Snelling.

Radiocarbon is the main international journal of record for research articles and date lists relevant to 14C and other radioisotopes and techniques used in archaeological, geophysical, oceanographic, and related dating. The journal is published quarterly. Radiocarbon Dating inaugurates a new series, "Interpreting the Past," published jointly by the British Museum and the University of California Press. Approaching archaeological techniques and artifacts from an interpretive viewpoint, the series looks in detail at specific classes of Reviews: 1. 1. Introduction. Since the early days of radiocarbon dating, bone proved to be a difficult material to deal with (Libby, ).Collagen extraction did not start until the seventies (Longin, ) and the dating of “bulk” carbon was the norm, often giving young y, scholars noticed that fossil bones could be infiltrated with secondary calcite and started to remove it using HCl Cited by: “When Willard F. Libby first discovered radiocarbon dating in , archaeologists, and especially Egyptologists, ignored it. They questioned its reliability, as it did not coincide with the "known" historical dates of the artifacts being tested.
