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 ...
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 ...
Thermoluminescent characterization of Al2O3-derived synthetic topaz
(Elsevier Science, 2016-12)
Albeit the thermoluminescent properties of both Al2O3 and natural topaz have been documented, owing to a controlled composition, the prospective of synthetic topaz for dosimetry applications is expected to be further ...
TL, EPR and optical absorption studies on natural alexandrite compared to natural chrysoberyl
(2002-10-19)
The TL, optical absorption (OA) and EPR properties of natural Brazilian alexandrite and chrysoberyl have been investigated. The TL measurements for natural alexandrite show five peaks between 100 and 450°C, with their ...
Dosimetric properties of UV irradiated calcium co-doped borate glass-ceramic
(ELSEVIER SCIENCE BV, 2008)
The thermoluminescence (TL) response of Dy and Li doped 20CaB(4)O(7)-80CaB(2)O(4) (Wt%) glass-ceramic irradiated with ultraviolet (UV) radiation was studied. In order to act as TL activator ions, the Dy and Li ions were ...
Dosimetric properties of UV irradiated calcium co-doped borate glass-ceramic
(Elsevier B.V., 2008-02-01)
The thermoluminescence (TL) response of Dy and Li doped 20CaB(4)O(7)-80CaB(2)O(4) (Wt%) glass-ceramic irradiated with ultraviolet (UV) radiation was studied. In order to act as TL activator ions, the Dy and Li ions were ...
Study of the gamma radiation response of watch glasses
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
Some dosimetric properties of watch glasses were studied applying the thermoluminescence technique. The watch glass samples were powdered, and the selected grains were mixed with Teflon (TM). The mixture was pressed and ...
Diagnostic reference levels for the most frequent radiological examinations carried out in Brazil
(PAN AMER HEALTH ORGANIZATION, 2009)
Objectives. A large-scale survey of doses to patients undergoing the most frequent radiological examinations was carried out in health services in Sao Paulo (347 radiological examinations per 1 000 inhabitants), the most ...
Dating archeological ceramics from the Valley of Vitor, Arequipa by the TL method
(TAYLOR & FRANCIS LTD, 2009)
The age of some ancient pottery from the Valley of Vitor in the region of Arequipa, Peru, is determined by the thermoluminescence (TL) method. For dating, a 325 degrees C TL peak was used and irradiation with -dose from 5 ...
