Thermoluminescence dating is generally not very accurate.The accuracy of thermoluminescence dating is only about 15% for a single sample and 7 to 10% for a suite of samples in a single context.A sample of the earth also needs to be collected so environmental radiation can be tested.The wetness of the soil and the sample should also be recorded.

Eventually, we will follow this formula to found out how many years old the sample is: Age (year) = accumulated dose / dose rate per year Thermoluminescence dating can be performed only in a specialized laboratory which will have a chemical section for the treatment of the samples with reagents and a radiation hazard restricted area.Electron trapping Energy absorbed from ionizing radiation frees electrons to move through the crystal lattice, where some are trapped at imperfections.Later heating releases the trapped electrons, producing light whose intensity is proportional to the amount of radiation absorbed.Create fake pottery that will pass the thermoluminescence test One way to pass a fake through a TL test is to expose the newly-made pottery to a high dose of artificial radiation sources, thus fooling the measurement instruments.However, producing fakes with this method calls for expertise on the subject, as well as expensive instruments.

Thermoluminescent Natural radioactivity causes the number of trapped electrons to build up.
