Assessment of Ge-doped optical fibre as a TL-mode detector
چکیده انگلیسی

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 a TL sensor like the dose- and dose rate-responses is examined. The presented studies show that germanium doped silica fibres have potential dosimetric properties and should be excellent TL-mode detectors in instances of radiotherapy (clinical dosimetry) and in-vivo radiation dosimetry as well in the field of nuclear facilities.


► The GeD2 fibre meets all the dosimetric criteria required by a TL-mode detector.
► Re-use of GeD2 optical fibre dosimeter without any particular regeneration treatment.
► No thermal quenching effect on the GeD2 fibre TL response.
► GeD2 fibre shows some dosimetric features better than those of the commercial TLDs.
