This process frees energy in the form of light, which can be measured.

By making multiple measurements (you need at least two for a date estimate) we can find out how much radiation the item was exposed to over the years and can get dating estimates related to when the item was last heated.

Here we come to the question of how accurate the dates are that we currently have regarding the history of the human race and our planet.

The various techniques are applicable under certain conditions, and yield variable results based on context and dated material.

All these dating techniques are focused on generating an absolute or relative chronology as the first step in understanding the past.

Estimating age in the archaeological record is the primary step in understanding the human past.
