Resumo
The properties of the thermoluminescent emission (TL) and thermally stimulated exoelectron
emission (TSEE) of pellets of colourless natural topaz. samples from Santo Antonio do Jacinto,
Minas Gerais, Brazil. were studied with the aim of use as solid state dosimeters. Standardized
fields of 6oCo, I3'Cs, 241Am, 90Sr/9"Y and X-rays were used for the tests. The TSEE and TL
responses were studied as a function of the radiation energy (photons and particles) and as a
knction of the absorbed dose. The results indicate that colourless topaz from Minas Gerais,
Brazil, is a promising material for dosimetric purposes.
