Thermoluminescence response of Ge- and Al-doped optical fibers subjected to low-dose electron irradiation

In this paper, we report quantitative features of the thermoluminescence (TL) responses of commercially available Ge- and Al-doped optical fibers subjected to low-dose electron irradiation. The TL response of Ge-doped optical fibers increases monotonically over the investigated dose range 0.02-0.24 Gy. The Ge-doped optical fibers have a greater response than the Al-doped optical fibers by a factor of at least 15. Results for the doped fibers are also compared with results for TLD-100
