Thermoluminescence Properties of Natural Mica—Biotite and Muscovite in Search of Dosimetric Application
In this article thermoluminescence (TL) properties of biotite and muscovite have been reported in details. Significant modifications in the trapping sites with pre-annealing treatment have been observed in both samples. Dosimetric characteristics of these minerals are also found to be improved significantly with annealing treatment. In biotite dose responses have been found to be linear from 10–1100 mGy and in muscovite 10–2000 mGy. For both the samples fading is high up to 5 days after irradiation, however decline after 5 days. Reproducibility in the results in both biotite and muscovite are found to be well enough to use as natural TL dosimeter.
