The older the pottery, the more radiation it has absorbed and the brighter the pottery sample glows.By measuring the TL, we can calculate how much radiation has been absorbed and use this information to calculate the approximate age of the pottery.
In all, close to two dozen physical quantities must be accurately measured to establish the relationship between doses of different kinds of radiation and light output, and to compute dose rate.Thermoluminescence (TL) dating can also be used to determine the age of pottery.The Lund Luminescence Laboratory was established in 2011, as the first of its kind in Sweden. The age of the pottery, in principle, may then be determined by the relation Age = Accumulated dose / Dose per year Although conceptually straightforward, TL has proven to to be far from simple in practice.
Should I be concerned about artificial irradiation? If the radioactivity of the pottery itself, and its surroundings, is measured, the dose rate, or annual increment of dose, may be computed.Sample discs are mounted on a wheel and the readers are programmed to run heating and irradiation sequences.
