By: Jessika Toothman. Prior to the development of radiocarbon dating , it was difficult to tell when an archaeological artifact came from. Unless something was obviously attributable to a specific year -- say a dated coin or known piece of artwork -- then whoever discovered it had to do quite a bit of guesstimating to get a proper age for the item. The excavator might employ relative dating, using objects located stratigraphically read: buried at the same depth close to each other, or he or she might compare historical styles to see if there were similarities to a previous find.

ORAU - Radicoarbon dating

Radiocarbon dating, invented in the late s and improved ever since to provide more precise measurements, is the standard method for determining the dates of artifacts in archaeology and other disciplines. Manning is lead author of a new paper that points out the need for an important new refinement to the technique. The outcomes of his study, published March 18 in Science Advances , have relevance for understanding key dates in Mediterranean history and prehistory, including the tomb of Tutankhamen and a controversial but important volcanic eruption on the Greek island of Santorini. Radiocarbon dating measures the decomposition of carbon, an unstable isotope of carbon created by cosmic radiation and found in all organic matter. Cosmic radiation, however, is not constant at all times. Tree-ring calibrated radiocarbon started to be widely used 50 years ago. A standard calibration curve was introduced in and is updated every few years as more data are added.

Radiocarbon Dating

Radiocarbon dating measurements produce ages in "radiocarbon years", which must be converted to calendar ages by a process called calibration. Willard Libby , the inventor of radiocarbon dating, pointed out as early as the possibility that the ratio might have varied over time. Discrepancies began to be noted between measured ages and known historical dates for artefacts, and it became clear that a correction would need to be applied to radiocarbon ages to obtain calendar dates. The term Before Present BP is established for reporting dates derived from radiocarbon analysis, where "present" is
