摘要

We carry out a comparison of the thermoluminescence (TL) response of photon and electron irradiated Ge- and Al-doped SiO2 optical fibres,as well as cross-comparison with that of TLD-100.Irradiation is made with 6 MeV electrons and 6 MV photons,for doses ranging from 0.2 Gy to 4.0Gy.The commercially available Al- and Gedoped optical fibres produce a linear dose-TL response.The TL yield for both of the doped fibres and also for TLD-100 is greater for electron irradiation than for photon irradiation.The TL yield of the Al-doped fibres is a small fraction of that of Ge-doped fibres (by a factor of 25),the Ge-doped fibres offering a response of 59％o of that of TLD-100.
