ANÁLISE TERMOLUMINESCENTE DE COMPÓSITOS DE CaSO4 ATIVADO COM TERRAS RARAS
Since the thermoluminescence started to be applied to the dosimetry of ionizing radiation in 1940 different materials detectors have been proposed, and one of the most common is CaSO4. The motivation of this work was to produce crystals of CaSO4 doped with rare earth elements such as europium (Eu),...

Since the thermoluminescence started to be applied to the dosimetry of ionizing radiation in 1940 different materials detectors have been proposed, and one of the most common is CaSO4. The motivation of this work was to produce crystals of CaSO4 doped with rare earth elements such as europium (Eu), neodymium (Nd) and thulium (Tm). It was also produced crystals of CaSO4:Ag. The interest in the production of these materials was to investigate other methods of production of thermoluminescent materials. The results show that the CaSO4:Tm is more suitable for use in the thermoluminescent dosimetry. Although not the most intense peak, the peak at 170 °C could be a dosimetric peak.
