摘要：

Nuclear industry may benefit from the implementation of Optical Fibre Sensor (OFS) technology. This is obvious if the OFS integrates features that meet specific nuclear sensing needs, such as distributed dose monitoring in underground radioactive waste disposals(1). The use of radiation sensitive fibres for dosimetry has already been proposed in literature(2). In this paper, we report on our gamma irradiation of such dedicated Ge-P co-doped and pure P-doped optical fibre, fabricated by the Fibre Optic Research Centre(3) (FORC) in Moscow. We show that after a careful selection of the wavelength at witch the radiation-induced attenuation is measured, it is possible to reconstruct the dose within 20 % accuracy by means of a linear model or a second order polynomial, depending on the temperature.
