By dividing the archaeological dose by the annual dose, we obtain the age of the last heating or insolation.Ī TL/OSL dating will include the measurement of the annual dose. ![]() Our researchers measure this quantity of irradiation by determining the concentration of radioelements (uranium, thorium and potassium) in the object and its environment. ![]() ![]() Consequently, the value of the annual dose can vary strongly from one context to another. This irradiation comes from the object itself (self-irradiation), from the close environment up to 1 m from the object, and from cosmic radiation. The annual dose is the dose of irradiation received by the material every year.
