It is good for dating for the last 50,000 years to about 400 years ago and can create chronologies for areas that previously lacked calendars.
In 1949, American chemist Willard Libby, who worked on the development of the atomic bomb, published the first set of radiocarbon dates.
When it comes to dating archaeological samples, several timescale problems arise.Chronometric dating techniques produce a specific chronological date or date range for some event in the past. Relative dating techniques, on the other hand, provide only the relative order in which events took place.For example, the results of dendrochronology (tree-ring) analysis may tell us that a particular roof beam was from a tree chopped down in A. For example, the stratum, or layer, in which an artifact is found in an ancient structure may make it clear that the artifact was deposited sometime after people stopped living in the structure but before the roof collapsed.For the most part, radiocarbon dating has made a huge difference for archaeologists everywhere, but the process does have a few flaws.For example, if an object touches some organic material (like, say, your hand), it can test younger than it really is.
More recently is the radiocarbon date of 1950 AD or before present, BP.
