Thermoluminescence (TL) materials exhibit a wide range of applications in different areas such as personal dosimetry, environmental dosimetry, medical research etc.Doping of different rare earth impurities in different hosts is responsible for changing the properties of materials useful for various applications in different fields. These materials can be irradiated by different types of beams such as γ-rays, X-rays, electrons, neutrons etc. Various radiation regimes, as well as their dose-response range, play an important role in thermoluminescence dosimetry. Several TL materials, such as glass, microcrystalline, nanostructured inorganic materials and recently developed materials, are reviewed and described in this article.

TSD current studies as a function of polarizing field (0-9 kV cm-1) and thickness (1000-7000 AA) of polyvinyl acetate thin films show depolarization peaks at 326, 389 and 468K (heating rate 6K per min) with activation energies 0.22, 0.39 and 0.66 eV and relaxation times 7.50*102, 9.12*103 and 3.70*106s at 300K, respectively. A correlation has been found between 326 and 389K peaks and the beta and the alpha relaxation process which are attributed to the motion of the side groups and the orientation of the dipoles of the main polymer chain, respectively. The peak at 468K is related to the alpha ' relaxation process and is due to the release of the trapped space charges.
