The care about safety of occupationally exposed workers, patients and the whole population is increasing due to the increasing use of ionizing and ultraviolet radiations have been used more often in several areas such as medicine, industry and research. This fact leads to unceasing search for new materials and dosimetric techniques to assure accurate dose measurements, taking into account their cost and their easy utilization. Nowadays, luminescent detectors are being frequently used mainly in personal dosimetry services, replacing the dosimetric films, but also in medical applications, in research and in retrospective dosimetry. Among luminescent dosimeters, the most utilized are those based on thermoluminescence (TL) and on optically stimulated luminescence (OSL). These detectors present, in general, many advantages, such as: high sensitivity, linear response for a wide range of doses, reuse and stability in environmental conditions.This project aims to study the dosimetric characteristics of materials not yet used in radiation dosimetry, such as natural materials, using luminescence techniques. Another objective is to determine the main dosimetric characteristics of extensively reported TL materials, using the OSL technique, in order to achieve optimal relation between cost, availability, convenience and reliability of results for an adequate choice of materials for environmental, area, individual, clinical and high dose dosimetry.
