This age is computed under the assumption that the parent substance say, uranium gradually decays to the daughter substance say, lead , so the higher the ratio of lead to uranium, the older the rock must be.

In the s samples were tested with AMS, yielding uncalibrated dates ranging from 11, BP to 11, BP, both with a standard error of years. This was demonstrated in by an experiment run by the British Museum radiocarbon laboratory, in which weekly measurements were taken on the same sample for six months. Radiometric dating relies on the properties of isotopes. Over the next thirty years many calibration curves were published using a variety of methods and statistical approaches.

The half-life of 14 C the time it takes for half of a given amount of 14 C to decay is about 5, years, so its concentration in the atmosphere might be expected to reduce over thousands of years, but 14 C is constantly being produced in the lower stratosphere and upper troposphere , primarily by galactic cosmic rays , and to a lesser degree by solar cosmic rays. The additional samples allow errors such as background radiation and systematic errors in the laboratory setup to be detected and corrected for.
