The use of pellets of brazilian natural topaz as radiation dosimeters. In: INTERNATIONAL CONGRESS ON MATERIALS, 2000, Johannesburg, South Africa. Disponível em: http://repositorio.ipen.br/handle/123456789/15179.http://repositorio.ipen.br/handle/123456789/15179The 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.openAccessdosimetrymineralsthermoluminescencestimulated emissionexoelectronsthermoluminescent dosemetersenergy dependenceradiation dosesTexto completo de eventohttps://orcid.org/0000-0002-7362-2455
