An investigation of the thermoluminescence of Ge-doped SiO2 optical fibres for application in interface radiation dosimetry.
We investigate the ability of high spatial resolution (∼120 μm) Ge-doped SiO2 TL dosimeters to measure photoelectron dose enhancement resulting from the use of a moderate to high-Z target (an iodinated contrast media) irradiated by 90 kVp X-rays. We imagine its application in a novel radiation synovectomy technique, modelled by a phantom containing a reservoir of I2 molecules at the interface o...
متن کاملTailored optical fibres
The paper defines the field of special optical fibers. Classification of tailored optical fibers was introduced. The characteristics of main families of such fibers were presented. There were discussed the following fibers: isotropic made of soft glass, of complex refraction – including ring-index, polarization maintaining and polarizing, elliptical, holey with macro holes and porous, nonlinear...
متن کاملThermoluminescence Response of Ge-Doped Cylindrical-, Flat- and Photonic Crystal Silica-Fibres to Electron and Photon Radiation
Study has been made of the thermoluminescence (TL) response of silica-based Ge-doped cylindrical, flat and photonic crystal fibres (referred to herein as PCF-collapsed) to electron (6, 12 and 20 MeV) and photon (6, 10 MV) irradiation and 1.25 MeV γ-rays, for doses from 0.1 Gy to 100 Gy. The electron and photon irradiations were delivered through use of a Varian Model 2100C linear accelerator lo...
متن کاملThermoluminescence characteristics of Ge-doped optical fibers with different dimensions for radiation dosimetry.
Important thermoluminescence (TL) properties of five (5) different core sizes Ge-doped optical fibers have been studied to develop new TL material with better response. These are drawn from same preform applying different speed and tension during drawing phase to produce Ge-doped optical fibers with five (5) different core sizes. The results of the investigations are also compared with most com...
متن کاملImplementation of an intraoperative electron radiotherapy in vivo dosimetry program
BACKGROUND Intraoperative electron radiotherapy (IOERT) is a highly selective radiotherapy technique which aims to treat restricted anatomic volumes during oncological surgery and is now the subject of intense re-evaluation. In vivo dosimetry has been recommended for IOERT and has been identified as a risk-reduction intervention in the context of an IOERT risk analysis. Despite reports of fruit...
