Thermoluminescence 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 کاملAn 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 کاملAssessment of Ge-doped optical fibre as a TL-mode detector
This study analyses the thermally stimulated luminescence or thermoluminescence (TL) glow curve between 300 and 773 K of germanium-doped silica optical fibre. A main glow peak at 530 K with a characteristic spectral emission centred at 400 nm is found. Both features are particularly suitable for dosimetry. Thus, an investigation by the TL technique of some first clinically relevant features of ...
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 کاملAssessment of Ge-doped optical fibres as a TSL-mode detector
This study analyses the thermally stimulated luminescence (TSL) or thermoluminescence glow curve between 300 and 773 K of germanium-doped silica optical fibre and finds a main glow peak at around 500 K with a characteristic spectral emission centred at 400 nm. Both features are particularly suitable for dosimetry. Thus, an investigation by the TSL technique of some first clinically relevant fea...
