Thermal illumination dating of pottery

thermal illumination dating of pottery-77

All sediments and soils contain trace amounts of radioactive isotopes of elements such as potassium, uranium, thorium, and rubidium.

These slowly decay over time and the ionizing radiation they produce is absorbed by mineral grains in the sediments such as quartz and potassium feldspar.

The samples were given different thermal treatments, followed by γ irradiation at room temperature, illumination with UV light at −100°C and readout of the TL signal.

ABSTRACT: In thermoluminescence (TL) dosimetry, the phosphor amethyst quartz as a thermoluminescent, appears to be one of the materials arousing the highest interest.

This is called de-airing and can be accomplished either by a machine called a vacuum pug or manually by wedging.
