By measuring the amount of carbon-14 in the annual growth rings of trees grown in southern Jordan, researchers have found some dating calculations on events in the Middle East – or, more accurately, the Levant – could be out by nearly 20 years.That may not seem like a huge deal, but in situations where a decade or two of discrepancy counts, radiocarbon dating could be misrepresenting important details.It can be applied to most organic materials and spans dates from a few hundred years ago right back to about 50,000 years ago - about when modern humans were first entering Europe.For radiocarbon dating to be possible, the material must once have been part of a living organism.By comparing the two categories of carbon in organic remains, archaeologists can judge how recently the organism that left them last absorbed carbon-14 out of its environment.Over millennia the level of carbon-14 in the atmosphere changes, meaning measurements need to be calibrated against a chart that takes the atmospheric concentration into account, such as INTCAL13.The net effect of this is that all living organisms have the same radiocarbon to stable carbon ratio as the atmosphere.
