Thermoluminescence flat optical fibers have been proposed as a radiation sensor in the high flux radiation field, e.g. nuclear reactor. It is also used as the medical dosimetry for both diagnostic and radiotherapy applications. Subsequently, a flat optical fiber contains pure silica SiO2 and doped (GeB) optical fibers were selected for this research. The proposed flat optical fibers shows admirable linear radiation response behavior within the medical relevant dose range for all of these energies, high-quality reproductivity, independence of radiation energy and dose rate and exhibits a very...

This research mainly is to investigate the effects of heating rate on the glow peak TL of optical fibers. Four kinds of optical fibers were investigated: pure silica (SiO2), germanium boron (GeB), 6% germanium (Ge) and TLD 100. The result indicates that the normalized TL response decreases with the increasing of heating rate. Also, it is recommended to use higher dose during TL measurement because of its higher normalized TL response. Some responses of glow peak parameters, such as peak integral, activation energy, maximum peak temperature were also evaluated in this study. The result found...
