THERMOLUMINESCENCE PROPERTIES OF Yb-Tb-DOPED SiO2 OPTICAL FIBER SUBJECTED TO 1.25 MeV GAMMA RADIATION
Abstract
A thermoluminescence (TL) analysis was carried out to study the sensitivity and dose responses of Yb-Tb-doped SiO2 optical fiber subjected to 1.25 MeV gamma radiation. The results are compared with the commercially available standard LiF:Mg,Ti (TLD-100) chip. The Yb-Tb-doped SiO2 optical fiber and TLD-100 chips were placed inside Perspex and irradiated with 1.25 MeV gamma photons with doses ranging from 1.0 to 10.00 Gy. The results clearly show the superiority of TLD-100 chips in terms of response and sensitivity. The sensitivity of Yb-Tb-doped optical fiber and TLD-100 chips is 45.25 and 768.85 nc/(mg × Gy) respectively.
