Abstract

ABSTRACT A radiation dosimeter based on Er-doped optical fibre is described. The thermoluminescence characteristics induced by ⁶⁰Co irradiation are investigated.These characteristics including reproducibility, photon dose response, minimum detectable dose, fading and annealing procedure.

Item Type:Journal
Additional Information:The Er-doped optical fibre shows a good linear range of the TL response as a function of the absorbed dose and has a very simple annealing procedure. The Er-doped optical fibre has a simple glow curve with well-defined peak around 150°C. However, it has a high fading rate where 30% of the signal is lost during the first 24 hours after the exposure.
Keywords:Er-doped optical fibre, Thermoluminescence
