The object to be dated is heated in a laboratory until it glows.

Some natural materials such as various stones and soils (and also things made from them, such as pottery and stone tools) absorb or 'trap' naturally occurring electrons from their surroundings.

The number of trapped electrons depends on the total amount of radiation that the mineral has been exposed to.

If we assume that the radiation dose rate of the sediment has remained constant over time, then if we measure that dose rate, we can calculate the sample age.

C dating, thermoluminescence is related to radioactive decay.
