14 carbon dating method
The older an object, the more trapped electrons it will have.
When the object is heated to 350 degrees Celsius the trapped electrons are released and this is called a clock resetting event.
The wetness of the soil and the sample should also be recorded.
Then we need to correlate thermoluminescence light to radiation dose rate per year which the sample has received since its last clock resetting event.Later heating releases the trapped electrons, producing light whose intensity is proportional to the amount of radiation absorbed.Measuring the intensity of the luminescence can determine how much time has passed since the last time the object was heated.TL is based on the fact that almost all natural minerals are thermoluminescent.Energy absorbed from ionizing radiation frees electrons to move through the crystal lattice, some of which are trapped at imperfections in the crystal lattice.
