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.

This means that a very small piece of material must be removed from the manuscript for testing and cannot be returned.

The calibrated date is also presented, either in BC or AD or with the unit cal BP (calibrated before present - before 1950).

The calibrated date is our “best estimate” of the sample’s actual age, but we need to be able to return to old dates and recalibrate them because new research is continually used to update the calibration curve.

Radiocarbon dates are presented in two ways because of this complication.

The uncalibrated date is given with the unit BP (radiocarbon years before 1950).

In the case of the Birmingham Qur’an, the result of 568-645 has 95.4% probability.
