Radiocarbon and Tree Ring Dating
Carbon dating techniques were first developed by the American chemist, Willard F. It is produced currently at a fairly constant rate in the upper atmosphere through the action of cosmic radiation on Nitrogen When they die, they no longer obtain more 14 C to incorporate, and so, the 14 C decays back into 14 N without being replaced. A ratio can then be established and compared with the known half-life of 14 C. Then an age can be obtained for the organic material. To understand this process we must first understand a little bit about the atoms themselves and how they get their names.
Radiocarbon After Four Decades pp Cite as. The field of dendrochronology has developed during the first decades of this century. Tree-ring dating was the only method of precise age determination until the s, when the radiocarbon dating method was developed. It is a fascinating chapter in the history of research to observe the immediate interdisciplinary cooperation between tree-ring dating and radiocarbon dating that started in the s and continues up to this day with increasing importance. This chapter presents a brief historical overview of the development of superlong Holocene tree-ring calendars and the calibration of the radiocarbon time scale derived from tree-ring measurements, with a synopsis of the actual stage of research.
