Abstract

Among the wide choice of radiation dosimeter that can be used for application in radiotherapy but thermoluminescence dosimetry (TLD) has now become a well-established technique for radiation dosimeter. More recently studies in thermoluminescence are in investigating and developing the commercial optical fiber as a TLD material. In this experiment, Al and Ge-doped optical fibres and TLD- 100 were used. The objective of this study is to investigate the thermoluminescence characteristics such as thermoluminescence response, sensitivity, stability and reproducibility of SiO2 optical fibres with various electron energies and doses. The TL results obtained will be compared with the commercially available TLD-100. The doped SiO2 optical fibres and TLD-100 are placed in solid phantom and irradiated to 7, 10 and 14 MeV electron beam at dose ranging from 0.2 Gy to 4.0 Gy using LINAC at Hospital Sultan Ismail, Johor Bahru. The TLDs will produce glow curves whose information are then analyzed. Al and Ge-doped optical fibres have a linear dose-TL signal relationship that is proportionality between the TL signal and the dose.
