Radiocarbon dates are presented in two ways because of this complication.The uncalibrated date is given with the unit BP (radiocarbon years before 1950).Some of the first radiocarbon dates produced showed that the Scottish tombs were thousands of years older than those in Greece.The barbarians of the north were capable of designing complex structures similar to those in the classical world.In addition, samples need to be thoroughly cleaned to remove carbon contamination from glues and soil before dating.

While the lighter isotopes C has decayed that what remains can no longer be measured. In 5,730 years half of the C in the atmosphere, and therefore in plants and animals, has not always been constant.In 2008 we could only calibrate radiocarbon dates until 26,000 years.Now the curve extends (tentatively) to 50,000 years.Professor Willard Libby produced the first radiocarbon dates in 1949 and was later awarded the Nobel Prize for his efforts.Radiocarbon dating works by comparing the three different isotopes of carbon.
