dc.description.abstractIn this work, the thermoluminescent properties of pellets containing powdered Wollastonite embedded in Teflon were studied. The preliminary results using gamma rays from a 60Co source showed linearity at the calibration curve between 0.5 Gy and 10 Gy. The main TL peaks are located at 125, 200 and 245 °C. The repeatibility of TL response presented a maximum coefficient of variation of 6.3%. The material can be used in successive irradiation-reading-annealing cycles without an appreciable change in its sensitivity. The calibration curve for a gamma source (60Co) up to 20 kGy and the minimum detection limits were obtained. The results show that these Wollastonite-Teflon pellets present possibilities for use as TL dosimeters.
