Description
Summary: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 60 Co, 137 Cs, 241 Am, 90 Sr/ 90 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 function of the absorbed dose. The results indicate that colourless topaz from Minas Gerais, Brazil, is a promising material for dosimetric purposes.
