Known as radiocarbon dating, this method provides objective age estimates for The “radiocarbon revolution” made possible by Libby's discovery greatly benefitted Their results predicted the distribution of carbon across features of the. to develop more precise historical chronologies that led him to radiocarbon dating in He was It showed all of Libby's results lying within a narrow.
The results they obtained indicated this was the case. The tests suggested that the half-life they had measured was accurate, and, quite reasonably, suggested further that atmospheric radiocarbon concentration had remained constant throughout the recent past. InArnold and Libby published their paper "Age determinations by radiocarbon content: Checks with samples of known age" in the journal Science.
In this paper they presented the first results of the C14 method, including the "Curve of Knowns" in which radiocarbon dates were compared with the known age historical dates see figure 1. The theoretical curve was constructed using the half-life of years. Each result was within the statistical range of the true historic date of each sample. In the s, further measurements on Mediterranean samples, in particular those from Egypt whose age was known through other means, pointed to radiocarbon dates which were younger than expected.
