(Since then new radiocarbon standards have been introduced, such as the Oxalic Acid I and II standards, which were correlated with the original standard, and after that, standards such as the Australian National University (ANU) sucrose standard.
Actually, the later established figure, known as the "Cambridge half-life", is 5730 40 years, whereas the initial figure established by Libby et al. (What is curious are the conclusions that Scott reaches in his article.
Having dutifully explained how C-14 is primarily created (i.e.
solar/cosmic neutrons striking nitrogen in the atmosphere thus converting it to C-14), he then manages to arrive at the odd assumption that carbon dating agrees with the YEC timescale of the Earth being only some 6,000 10,000 years old.
Please note this is less than two half-lives of C-14, which will become important as we delve further into Scott's article.
Dendrochronology has been the most widely used calibration method, which uses tree-ring data overlapping between various sources, where certain ages can be reliably determined independently of C-14, and then cross-checked with C-14 dating.
