Radiometric dating vs carbon dating

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

A huge amount of work is currently underway to extend and improve the calibration curve.

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.
