Electron trapping Energy absorbed from ionizing radiation frees electrons to move through the crystal lattice, where some are trapped at imperfections.

Then we need to correlate thermoluminescence light to radiation dose rate per year which the sample has received since its last clock resetting event.

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.

Instead, a less sophisticated method that would deceive TL testing is to reuse original broken and unmarketable pieces.

Forgers commonly use the bottom of an original broken vessel, which has no commercial value, and make a new fake vessel on top of it.

Samples should be placed in a polyethylene bag and sealed with electrical tape.

To test the date we need to measure the sample’s thermoluminescence light which is then correlated to the accumulated dose of ionizing radiation.

Energy absorbed from ionizing radiation frees electrons to move through the crystal lattice, some of which are trapped at imperfections in the crystal lattice.

Later, heating releases the trapped electrons, producing light.

When the object is heated to 350 degrees Celsius the trapped electrons are released and this is called a clock resetting event.
