摘      要：We present the characteristics of the thermoluminescence (TL) response of Ge-doped optical fibers with various energies and exposures of photon *** investigate the Ge-doped SiO2 as an efficient TL material,the TL responses are compared with commercially available standard TLD100 *** Ge-doped optical fiber and TLD100 are placed in gelatin capsules and irradiated with x-ray using a Toshiba model KXO-15R x-ray *** Ge-doped fiber and TLD-100 show linear response as a function of current and time using x-ray photon of energy 60,80 and *** irradiated with 60,80 and l00kV x-ray energy at various currents (mA ),tube distance (cm) and exposure time (second) ranges,TLD100 media provide a TL yield up to two times that of Ge-doped *** energy response of the Ge-doped fibers is linear and similar over the 60-l00 kVenergy range,and its sensitivity is 0.39±0.05 of the TLD100 *** glow curves of TLD 100 and doped optical fiber are also compared.
