to the West and the Arch of Titus to che East; the sequence of human occupation in this residencial area, from medieval times down to the earliest phases of roman history, has been reconstructed. For setting up the dating thermoluminescent system of the Physics Department, several samples from excavation have been studied by the quartz inclusion technique. Since the archaeological age is in the range 630-580 B.The main results obtained during excavations consist in the discovery of remains of large houses, facing the and dating back to the 2nd half of the 6th century B. The average TL age of the site gives a value of 603 B. C., the TL data are in good agreement with the historical values.The method is a direct dating technique, meaning that the amount of energy emitted is a direct result of the event being measured.Better still, unlike radiocarbon dating, the effect luminescence dating measures increases with time.To obtain a truly absolute chronology, corrections must be made, provided by measurements on samples of know age.The most suitable types of sample for radiocarbon dating are charcoal and well-preserved wood, although leather, cloth, paper, peat, shell and bone can also be used.Beach nourishment is a problem worldwide and receives large amounts of attention due to the millions of dollars spent yearly in order to keep beaches beautified for tourists, e.g., in Waikiki, Hawaii.Sands with sizes 90-150 μm (very fine sand) were found to migrate from the swash zone 67% faster than sand grains of 150-212 μm (fine sand; Figure 3).

The theory of the method is presented and experimental results are given.

Luminescence dating (including thermoluminescence and optically stimulated luminescence) is a type of dating methodology that measures the amount of light emitted from energy stored in certain rock types and derived soils to obtain an absolute date for a specific event that occurred in the past.

This phenomenon has been applied in the thermoluminescent dosimeter, a device to measure the radiation dose received by a chip of suitable material that is carried by a person or placed with an object.

Thermoluminescence is a common geochronology tool for dating pottery or other fired archeological materials, as heat empties or resets the thermoluminescent signature of the material (Figure 1).
