    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.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.Some of the first radiocarbon dates produced showed that the Scottish tombs were thousands of years older than those in Greece.

    This is particularly important for very old samples.

    From these records a “calibration curve” can be built (see figure 2, below).

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

    In this way large domed tombs (known as tholos or beehive tombs) in Greece were thought to predate similar structures in the Scottish Island of Maeshowe.

    This supported the idea that the classical worlds of Greece and Rome were at the centre of all innovations.
