If 1% of the carbon in a 50,000 year old sample is from a modern contaminant, the sample will be dated to around 40,000 years.

Because of this, radiocarbon chemists are continually developing new methods to more effectively clean materials.

In addition, samples need to be thoroughly cleaned to remove carbon contamination from glues and soil before dating.

This is particularly important for very old samples.

Moving away from techniques, the most exciting thing about radiocarbon is what it reveals about our past and the world we live in.

Radiocarbon dating was the first method that allowed archaeologists to place what they found in chronological order without the need for written records or coins.

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

A huge amount of work is currently underway to extend and improve the calibration curve.In 2008 we could only calibrate radiocarbon dates until 26,000 years.
