“…It is noticed at the lower dose range 0.1-0.3 Gy that the sensitivity of the Er-doped silica CF is highly dependent on the radiation dose, gradually decreasing with doses above 0.4 Gy. This finding is consistent with the study by Alawiah et al (2015a) in which it was stated that the TL sensitivity of Tm-doped silica CF and pure silica CF is highly dependent on the radiation dose at the lower dose range 0.2-1 Gy, becoming more constant with doses above 2 Gy.

“…From previous study using Tm-doped silica CF, sub-linear response was observed over the dose range of 0.1-10 Gy for both 21 MeV electrons and 10 MV photons (Alawiah et al, 2015a). While, in yet one other study using 6 MV photon radiation, it was observed that pure silica flat fiber showed linear TL response up to 2 Gy (Alawiah et al, 2015b).…”

“…At lower energies fiber of any core diameter has a greater TL response and greater efficiency than that at higher photon energies (Bradley et al, 2012). The TL response of silica optical fibers under irradiation are influenced by many factors, including: the preform manufacturing conditions, the fabrication parameters used in producing the optical fiber, the preform deposition temperature, fiber drawing process characteristicsdrawing speed, fiber drawing tension, furnace temperature, oxygen-to-reagent ratio (Girard et al, 2007), dopants present in the optical fiber core or cladding (pure silica, or doped) (Alawiah et al, 2015a(Alawiah et al, , 2015bMady et al, 2010;Paul et al, 2009) and the type of radiation to which the optical fiber is exposed Yaakob et al, 2011;Hashim et al, 2010).…”

“…Several materials such as germanium [10], [53]- [57], boron [52], [58], aluminum [54], [59], [60], phosphorus [61], and thulium [60], [62] have been proposed for radiation dosimetry for different applications. Modified chemical vapor deposition (MCVD) is one of the common methods for doping such materials in silica fibers.…”

In this paper, we review the highly promising silica glass, fabricated as doped and undoped optical fiber for intended use in radiation dosimetry. The dosimetry techniques reviewed here, underpinned by intrinsic and extrinsic defects in silica glass, focus on Thermoluminescence (TL), Optically Stimulated Luminescence (OSL) and Radioluminescence (RL), with occasional references to the much more established Radiation Induced Attenuation (RIA). The other focus in this review is on the various materials that have been reported earlier as dopants and modifiers used in silica glass optical fiber radiation dosimeters. This article also elaborates on recently reported optical fiber structures, namely, cylindrical fibers, photonic crystal fibers and flat fibers, as well as dimensions and shapes used for optimization of dosimeter performance. The various types of optical fiber radiation dosimeters are subsequently reviewed for various applications ranging from medical dosimetry such as in external beam radiotherapy, brachytherapy and diagnostic imaging, as well as in industrial processing and space dosimetry covering a dynamic dose range from μGy to kGy. Investigated dosimetric characteristics include reproducibility, fading, dose response, reciprocity between luminescence yield to dose-rate and energy dependence. The review is completed by a brief discussion on limitations and future developments in optical fiber radiation dosimetry.
