by Dr Carl Wieland An attempt to explain this very important method of dating and the way in which, when fully understood, it supports a ‘short’ timescale.
Because of this relatively short half-life, radiocarbon is useful for dating items of a relatively recent vintage, as far back as roughly 50,000 years before the present epoch.
The model of radiocarbon dating which Libby developed, using his incorrect ‘uniform’ assumption, must therefore be corrected to fit the facts about C to start with, so they have an even greater error.
In other words, the further you go back, the more you have to shrink the radiocarbon dates to make them fit the facts.
has upset the natural carbon balance by releasing huge quantities of C ratio was like before the industrial revolution, and all radiocarbon dating is made with this in mind.
How do we know what the ratio was before then, though, say thousands of years ago?As soon as it dies, however, the C ration gets smaller.
