A comparative thermoluminescence and electron spin resonance study of synthetic carbonated A-type hydroxyapatite
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
Intensity of the 150 degrees C thermoluminescence peak of beta-irradiated carbonated synthetic A-type hydroxyapatite is approximately 12 times higher than that of the noncarbonated material. Deconvolution of the glow curve ...
Thermoluminescence of aluminophosphate glasses in the metaphosphate composition
(Elsevier B.V., 2006-05-01)
Potassium aluminum phosphate (KAP) glasses in the system xKPO(3)-(100-x)AI(PO3)3 with x = 10, 30 and 50 mol% were prepared in the metaphosphate composition. The glasses were doped with MnO2 and their thermoluminescent (TL) ...
325 degrees C thermoluminescence peak growth in quartz related to oxygen vacancies
(Gordon Breach Sci Publ Ltd, 1998-01-01)
The thermoluminescence intensity as a function of gamma-ray dose of the 325 degreesC peak, in quartz grains extracted from sea sediments and from fluvial aeolic dunes, is studied. It is found that the response curve at low ...
In vivo dosimetry with thermoluminescent dosimeters in external photon beam radiotherapy
(PERGAMON-ELSEVIER SCIENCE LTD, 2010)
The ultimate check of the actual dose delivered to a patient in radiotherapy can only be achieved by using in vivo dosimetry. This work reports a pilot study to test the applicability of a thermoluminescent dosimetric ...
Thermoluminescence measurements of entrance surface skin dose in exams of dog's chest in veterinary radiology
(Pergamon-Elsevier B.V. Ltd, 2010-03-01)
This study aims to determine the entrance surface skin doses in dogs (with suspected pulmonary metastasis) submitted to chest X-rays using the technique of thermoluminescence (TL) dosimetry. Twenty seven radiologic exams ...
Thermoluminescence properties of natural zoisite mineral under gamma-irradiations and high temperature annealing
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
Natural silicate mineral of zoisite, Ca(2)Al(3)(SiO(4))(Si(2)O(7))O(OH), has been investigated concerning gamma-radiation, UV-radiation and high temperature annealing effects on thermoluminescence (TL). X-ray diffraction ...
Thermoluminescent and optical absorption properties of neodymium doped yttrium aluminoborate and yttrium calcium borate glasses
(ELSEVIER SCIENCE BVAmsterdam, 2009)
Neodymium doped yttrium aluminoborate and yttrium calcium borate glasses were prepared by the conventional melting-quenching technique with neodymium concentration varying from 0.10 to 1.0 mol%. The obtained glasses present ...
Correlation between electron paramagnetic resonance and thermoluminescence in natural sodalite
(SPRINGER, 2010)
Samples of natural sodalite, Na(8)Al(6)Si(6)O(24)Cl(2), submitted to gamma irradiation and to thermal treatments, have been investigated using the thermoluminescence (TL) and electron paramagnetic resonance (EPR) techniques. ...
Thermoluminescence, electron paramagnetic resonance and optical absorption in natural and synthetic rhodonite crystals
(SPRINGER, 2008)
Thermoluminescence, electron paramagnetic resonance and optical absorption properties of rhodonite, a natural silicate mineral, have been investigated and compared to those of synthetic crystal, pure and doped. The TL peaks ...
Thermoluminescence and optical absorption studies of natural grossular minerals
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
The optical absorption spectra of two samples of grossular have been measured at room temperature. An intense charge transfer band (UVCT) of iron extends to the visible and near infrared region. Some peaks associated to ...
