Thermoluminescence dating ceramics
For example, a "Tang" dynasty item may show an age of 2000 years.
This would expose the fact that it was artificially irradiated.
However, as soon as a way is found to accurately "add" the proper radiation dose, the thermoluminescence dating method is not reliable anymore.
Application of this method of age determination is limited to those periods of pottery and fired clay availability ( from about 6000 BC to the present).

Particle physics is a science that is still too young to have reliable data going back such long time.

Thermoluminescence dating is based on the principle that natural radiation is stored by means of electrons in the crystal lattice of quartz or other minerals present in stone and other deposits.
