Description
Different colored jasper samples from Brazilian mines were powdered and mixed with teflon (composites jasper-teflonTM). This paper describes a preliminary study of a thermoluminescent method (TL) to verify the possibility of their use as high dose dosimeters or irradiation indicators in industrial areas. The jasper samples were exposed to different radiation doses, using the gamma-cell 220 system (60Co) of IPEN. The TL emission curves of samples presented two peaks at 130 °C and 190 °C. Calibration curves were obtained for the jasper samples between 50 Gy and 20 kGy. All five types of jasper samples showed their usefulness as irradiation indicators and as high-dose dosimeters. - Highlights: ► Jasper samples may be used for high dose dosimetry. ► Different colored Brazilian jasper samples were studied for radiation dosimetry. ► The basic advantage of jasper samples for dosimetry is their very low cost.
