Absolute dating archeology
Inscribed objects sometimes bear an explicit date, or preserve the name of a dated individual. However, only a small number of objects are datable by inscriptions, and there are many specific problems with Egyptian chronology, so that even inscribed objects are rarely datable in absolute terms.In the archaeology of part-literate societies, dating may be said to operate on two levels: the absolute exactness found in political history or 'history event-by-event', and the less precise or relative chronology, as found in social and economic history, where life can be seen to change with less precision over time.The first method was based on radioactive elements whose property of decay occurs at a constant rate, known as the half-life of the isotope.Today, many different radioactive elements have been used, but the most famous absolute dating method is radiocarbon dating, which uses the isotope C.The isotope of Potassium-40, which has a half-life of 1.25 Billion years, can be used for such long measurements.The dating of remains is essential in archaeology, in order to place finds in correct relation to one another, and to understand what was present in the experience of any human being at a given time and place.The contrast might also be drawn between two 'dimensions', the historical, and the archaeological, corresponding roughly to the short-term and long-term history envisaged by Fernand Braudel.
In a stratigraphical context objects closer to the surface are more recent in time relative to items deeper in the ground.

When it comes to dating archaeological samples, several timescale problems arise.
Archaeological Dating Methods introduces students to many of the more common dating methods used or found in related literature.
Most of the summarized dating methods may not be used with regularity in the field, but individuals should be informed about their existence, usefulness, and sample collection methods.
This method includes carbon dating and thermoluminescence.
