A similar effect can be brought about by stimulating the sample with infrared light.The intensity of thermoluminescence is directly related to the amount of accumulated changes produced by background radiation, which, in turn, varies with the age of the sample and the amount of trace radioactive elements it contains..These energy charged electrons progressively accumulate over time.When a sample is heated to high temperatures in a laboratory, the trapped electrons are released and return to their normal positions in their atoms.Such contamination can occur if a sample is exposed to carbon compounds in exhaust gasses produced by.

In this way, the confidence level of the dating is significantly increased.However, paleoanthropologists rarely use it to date sites more than several million years old.rock, soil, and clay produce constant low amounts of background ionizing radiation.The atoms of crystalline solids, such as pottery and rock, can be altered by this radiation.Specifically, the electrons of quartz, feldspar, diamond, or calcite crystals can become displaced from their normal positions in atoms and trapped in imperfections in the crystal lattice of the clay molecules.
