Radioactive decay can be used as a “clock” because it is unaffected by physical (e.g. For instance, the amount varies according to how many cosmic rays reach Earth.

This is affected by solar activity and the earth’s magnetic field.

These new techniques can have a dramatic effect on chronologies.

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.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.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.
