The thermoluminescence characteristics and the glow curves of thulium doped silica fiber exposed to 10 MV photon and 21 MeV electron radiation

The thermoluminescence (TL) glow curves and kinetics parameters of Thulium (Tm) doped silica cylindrical fibers (CF) are presented. A linear accelerator (LINAC) was used to deliver high-energy radiation of 21 MeV electrons and 10 MV photons. The CFs were irradiated in the dose range of 0.2–10 Gy. Th...
