Abstract
In consideration of the extensive use of thermoluminescence dosimetry in environmental monitoring, the aim of the present work is to report some experimental observations on the fading of some thermoluminescent materials as a function of the storage temperature. The study has been carried out for two different temperatures: room temperature (20 oC) and 40 oC, considering the second as the maximum average temperature that can be found in several countries. The materials used in the experiments were CaSO4/LiF:Dy, CaSO4:Dy (TLD-900), CaF2:Tm (TLD-300) and CaF2:Dy (TLD-200). These materials have been studied because of their high sensitivity and consequent convenience for environmental dosimetry.
