Abstract
This study investigates and compares the results of thermoluminescence responses, its linearity, sensitivity with various dose ranges and TL glow curve of Fluorine-doped silica fiber and TLD-100 materials. The TL responses of the Fl-doped silica fibers and TLD 100 were kept in gelatin capsule and irradiated with 6-MV photon at the dose range from 0.5 Gy to 4.0 Gy. Siemens model Primus 3368 linear accelerator located at Hospital Sultan Ismail; Johor Bahru has been used to deliver the photon beam to the samples. The TL-signal of TLD 100 media exhibits a significant linear dose to signal relationship with an increase in doses. The sensitivity of Fl-doped optical fiber is negligible to TLD 100 media.
