    Characterization of Brazilian Wollastonite for radiation dosimetry
    2006 - SOUZA, DIVANIZIA N.; MELO, ADEILSON P.; GAZANO, VANESSA S.O.; CALDAS, LINDA V.E.
    In these work preliminary results of the characterization analyses of Brazilian Wollastonite for radiation dosimetry are presented. Wollastonite is a silicate of calcium, Ca[SiO3], and it was acquired in the form of rude mineral with Andradite inclusions. The sample was cleaned and prepared for obtained selected grains of Wollastonite. The analyses of chemical and mineralogical compositions were obtained using the neutron activation and X-ray powder diffraction techniques. The thermoluminescent (TL) glow curves of the material shows a prominent peak at about 200°C. TL emission spectra, and photoinduced emission spectra were al so obtained.
