Absolute radiometric dating

This low concentration will mean your counting statistics will not be as robust and may result in decreased precision.

Early attempts at establishing an absolute time scale utilized the following concepts: declining sea levels, cooling of the Earth, cooling of the Sun, Earth tidal effects, sediment accumulation, and changes in ocean salinity.

In order to do this, you need to measure various isotopes of uranium .

Though, when you come to do this measurement you find that uranium concentrations are very low in your sample (on the order of a few parts per million).

The age we come up with is around 50 000 years old.
